WISELAZER ‎A30 4K Projector

I was keen to see how the new WISELAZER A30 compares to my current projector, the WiMiUS P28, which when I bought it was priced around the same as this one.

In the box were the projector, infrared remote control, UK Power Cable, HDMI Cable, two air filters (one fitted), cleaning cloth and a nicely printed and well-written User Guide. The best way to learn about what this unit does and how to use it is to study the User Guide, and so I include a scan of it in my video.

Build quality seems fine, the unit is smaller than my current one, which quite large and ungainly, but it is still substantial enough to feel hefty and robust enough to absorb the odd knock. The projector itself is pretty minimalist with an attractive dark grey matt finish with the only button one for power on the top surface. On the back are two USB ports, two HDMI ports, audio out and power-in ports and an infrared receiver. On one side is the air filter intake and on the other is the air filter outlet and recessed knurled focusing ring. On the base are the mounting points hidden behind removable plugs, the access panel for the air filter and the rake angle adjustment knob. The remote is full-sized with proper clicky buttons and is simple and intuitive to use. Sadly there is no tripod mount hole on the underside, which is a pity and a hard to understand omission.

Natively, the unit supports 1920 x 1080P resolution but will downscale 4K files seamlessly enough. I found that some file types were not recognised when played directly through USB but since I use the projector with an HDMI connected Fire TV stick -with an adjacent USB port to power it – this was not an issue. Although the projector itself has a 5G wifi connection, the Fire TV stick’s built-in wifi gives me all I need both from the internet and my network NAS as well as giving good quality in-sync audio.

Audio comes from two built-in speakers and is good quality and although not super loud it still easily drowns out the pleasingly muted fan noise. The projector has built-in Bluetooth and this gives me the option to use external Bluetooth speakers, although in use I find it more convenient to connect them to the Firestick’s own Bluetooth. The native 5G wifi allows for OTA firmware updates as well as phone and other smart device connections.

Although it is slightly less bright than my old projector this is more than made up for by the increased contrast ratio of 12000:1 compared to 8000:1 of my old machine. The is a real advance with more shades of black and gradations of white visible that gives far less muddy nighttime scenes and fewer burnt-out skies.

Video quality is excellent with a wall-filling image bright enough for curtains drawn daytime use. At night the image is even better as regards colour, dynamic range and contrast. The image from this projector beats my current one and is both sharper and more detailed with no sharpness fall off away from the centre and with improved saturation without bleeding or overload. I find text far easier to read across the whole screen than with my old projector which has a distinct sharpness loss toward the screen edges. Text on the WISELAZER is sharp across the entire screen.

The image size can be zoomed directly from the remote control. Likewise the remote can be used for manual 4-Point Keystone & ± 45° Keystone Correction to compensate for image distortion when the projector lens and screen are not correctly aligned. These features are important to allow the projector to be positioned conveniently whilst still giving a wall filling well proportioned image.

This is an excellent projector with superb image quality, decent sound and a good range of features including mirroring from both Android and Apple smartphones. Some users may mourn the lack of physical controls on the projector itself but I am not one of them as I much prefer to operate the device from the handset.

This is a superb projector for the £299 price and gives great results. Pair it with a Fire TV stick, Apple TV or Roku and it becomes a viable alternative to a big screen TV costing many times the price. I would be quite happy to buy this projector again and would not waste too much time trying to find a better one.

LHBD S12 True Wireless Earbuds

This new stem design true wireless headset from LHBD is nicely presented with high-end looks and a classy feel to it But is it any good?

There used to be a time when you had to pay plenty to get decent quality True Wireless Earbuds but the introduction of Bluetooth 5.0 seems to have changed all that. Before Bluetooth 5.0 all but the most expensive TW earbuds would continually drop out, crackle, pop and generally prove more trouble than they were worth. As technology develops each pair is better than the last and this new set is well configured with some of the latest tech on board.

In the box were the two buds together with a short USB charging cable, cleaning cloth, charging case and a well written and easy to read User Guide. Despite the light weight, everything has a distinctly premium and upmarket feel to it with first-rate build quality but without the weightiness of some rivals.

First time pairing could not be simpler and took just a few seconds. Subsequently, taking the buds from the case powers them on, they connect to each other and to the phone automatically, returning them to the case turns them off and begins charging. The smaller than average 300mAh Lithium-ion case battery can still recharge the buds up to 4 times. There are LED’s on each bud to show charging and connection status and the buds will charge automatically when placed into the case. Unlike with many smooth-skinned rivals, these stem buds are easy to remove from the case and holding the stem prevent accidental button presses, for me a major selling point. Unlike most rivals, these buds are easy to reset by long-pressing the button on the rear of the case.

These earbuds use the latest Bluetooth 5.1 technology which is currently only supported by the latest high-end smartphones but of course, they will also work with older Bluetooth devices. Bluetooth 5 adds a longer range and greatly improves both the stability of the wireless connection and battery life.

The buds are small, neat and comfortable to wear and will deliver up to 4 hours of music per charge. Sound quality is excellent for a TW headset with a very decent level of bass together with clean mid-tones and a sibilance free high end. Calls were clear to hear and easy to make. Call quality was fine at each end of the conversation with no dropouts or excessive background noise.

Each bud has a single soft touch button on it which can be used to end/reject calls, play/pause music, navigate tracks, alter volume and invoke your phone’s voice assistant. This works well and is easy to use. They are rated as IPX6 water-resistant which means they should be fine in the rain but not for swimming.

For the £20.99 price (slightly dearer than when I bought it), this headset compares very well with the high-end rivals I have tried as regards sound quality and features. Indeed, you would have to go a long way to find a better True Wireless Headset

Facamword Mini Wifi Spy Camera

This really is the nearest to a true Spy Camera I have yet tested and although it has some limitations for the current Amazon price of £45.99 it bears serious consideration for those needing a specialised security camera.

In the rather plain product box was just the camera itself, a charging cable and a detailed and comprehensive User Guide, Build quality throughout seems first-rate although due to the nature of the spy camera design best handled carefully.

The camera consists of a 66 x 25 mm control box with a short hard-wired flexible antenna on one end and a 199 mm flexible plastic strip with a tiny lens, about the size of a little fingernail, on the end. Both the antenna and lens strip seem rather delicate, so treat them with care. The camera can be powered by the internal rechargeable 300mAh battery or through a USB cable to a mains adapter or Powerbank. Expect to get about an hour of continuous use between charges. A tiny LED inside the main body of the device confirms charging status. On the body of the device are the only controls which are easy to operate and clearly marked, an Off/On switch and a reset button. Also on the main body of the device is the micro-SD card slot which (unlike most of the spy cameras I have tried) is easy to access and simple to use and will take a card of up to a generous 128Gb in size.

The camera will begin recording as soon as it is switched on but the best results are obtained by setting it up and controlling it through the excellent HomeEye App. The app is well designed and simple to use although let down slightly by some poorly translated instructions. With the app, you can control the camera either directly by connecting to the Wifi hotspot generated by the camera or over the internet after first connecting the camera to your home network.

Configuring the camera through the app is simple enough and the app will walk you through this. Firstly, connect your smartphone to the camera Hotspot and then if you wish remote access follow the instructions to connect it to your home wifi. You can now start recording in HD, standard or low quality with audio on or off. You can download and save video and images to the phone from the camera and from within the app export them to YouTube or other online locations. You can also enable Motion Detection on the camera to record 30 seconds clips and send alerts to your phone when motion is detected. You can also adjust the brightness and contrast and microphone volume of the camera as well as turn the status LED on or off and enable recording time stamps. The camera does not have much exposure tolerance and the settings need to be changed from location to location to allow for this and it is crucial for best results.

What are the results like?
Due to the tiny lens and the lack of any stabilisation, even the smallest movement leads to violent camera shaking and this together with the sensitive lens and slow shutter speed of around 15fps means the camera is not well suited for use on the move. To get the best results the camera needs to be in a static position with the brightness and contrast carefully set up in advance. Of course, you are never going to get great video and audio from this camera and given the nature of the device and the price it is foolish to expect it but with care, you can get perfectly acceptable results. I was very pleasantly surprised by the quality of the video I was able to obtain. The built-in microphone works OK but the levels are low and will need to be boosted at the editing stage but again are acceptable enough for a camera of this type.

The main selling point of this camera is the tiny size of the lens itself. If you can hide the body and antenna out of the way the lens is pretty hard to spot even if you are looking for it. Although the internal battery life gives about an hour of continuous use, it will operate continuously when connected to a USB adapter or power bank. It can work on a standalone basis or with remote control over the internet and would be perfect to monitor your home or office if theft is suspected.

I think that had I spent more time fine-tuning the camera settings and the positioning I would be able to get even better results. I know the camera is able to produce decent quality recordings but careful attention must be made to achieve it.

The camera is very small and can be easily hidden away for concealed use. It gave me better results when used indoors and indeed as the camera is not waterproof I suspect it is not really designed for outdoor use.

If you need a small and discreet spy camera for indoor fine weather outdoor use and are prepared to put the time and effort into getting the best results possible, then this could be what you are looking for and at a very attractive price too.

Sofirn SC21 Compact LED Flashlight

This truly pocket-sized little flashlight has a robust aluminium body, is fully rechargeable, offers multiple operating modes, is shock and water-resistant and is perhaps the brightest torch I have seen of this size.

In the box are the torch itself, 16340 battery, Type-c Charging Cable, Lanyard, Pocket Clip, two spare O-rings and a well written if rather complex user guide. Surprisingly for the £35.99 price no protective case was included.

It is exceptionally robust and well made with an aerospace grade 6061 aluminium alloy body that is IPX8 water resistant and 1 meter drop shock resistant at least. It can be immersed in water up to 2m deep for up to half an hour but is not suitable for diving.

It has a range of operating modes which can be a bit confusing to set up but basically, it can be set to either three light levels or stepless brightness, but most users will probably just use the maximum power Turbo mode. Click the single button twice to jump straight to Turbo mode, long press then click to access the other brightness modes.

So how bright is it?
I had doubts about the claimed 1000 Lumens output but I am convinced now and it amazes me just how much light comes out from the tiny body. There is a trade off for the power and when set to Turbo power you get just 1 hour from a single charge but this can be extended to up to 85 hours when less demanding modes are used. The light output is rated at 5000 K which gives a medium cool light perfect for general use.

The torch takes a single rechargeable 16340 battery which is included and can be replaced when necessary. I was pleased to see that the latest USB-C port has been used for charging and that a suitable (if rather short|) cable was included for this purpose. A status LED changes colour from red to green to indicate charging progress and when in use a low battery warning LED is present. A standard non-rechargeable CR123A can be used in an emergency but with a limited light level for a short time only, although I have not tested this.

At just 73mm in length and with a clip for that purpose, the torch can easily be kept in a pocket or car glove compartment for use when needed. This is the sort of item you can just tuck away somewhere and when the power goes off hunt it out.

Although not inexpensive, the build quality and sheer power of the little torch makes the price of £35.99 seem not at all unreasonable.

VogerIPC Outdoor Security Camera VG360

The rebadged VG360 outdoor camera from VogerIPC is robustly made, attractively designed, easy to configure over Wifi or Ethernet and offers very decent video quality along with smart motion tracking and a well designed and simple to use Android and iOS app.

In the box are the camera itself, screw-in antenna, UK Power Supply, fitting kit with screws and plugs, screwdriver, and a nicely printed and well-written User Guide. Although lightweight, build quality seems fine and the camera has an attractive and traditional design. It has a silk white plastic finish but the build quality seems good. On the front is PTZ the lens with Night Vision LEDs, an LED to show Wifi and power status and the microphone opening. Below the lens and hidden when the lens is pointing down, is a panel protecting the SD card slot and reset button. Use the screwdriver provided to open the panel. On the rear at the back is the screw adapter for the wifi antenna. Inside the base are the ethernet input port, USB power connector cable outlet. Unlike most cameras of this type no external mains power supply is needed as the device is entirely USB powered with a standard USB adapter plug included. The camera is rated IP66 weatherproof which means it should be fine with anything short of water immersion.

Although it has a budget price and simple design I was pleased to see that unlike many rivals this camera has an ethernet interface as well as wifi. It is always better to go with an ethernet cable connected to the router as this gives a faster and more stable signal as well as making for an easier initial setup. The optional wifi antenna can be left off for a neater look when ethernet is used.

The first thing to do is to download and install the widely used and well respected Tuyasmart app, I tested using the Android version with a wifi connection. You have to register the app before use but doing so is free and you can use a disposable email address to do so. Take note to ensure the phone used to configure the camera is connected to a 2.4Ghz network, not 5Ghz, which this camera does not support. You can also install it, as I did, using an ethernet cable and then add the wifi details later. After installing and registering the app and plugging in the camera follow the in-app instructions to add a new camera. After inputting your home wifi details the app automatically and very quickly sends this to the camera which then connects automatically to the wifi network with on-screen and voice confirmations throughout. It is worth noting that the camera will also work with the equally widely used Smart Life app.

This model has a clean 1080P image quality which is clearly not the upscaled 720p of some lesser rivals. Video quality from the 355° horizontal and 110° vertical rotating wide-angle 3.6mm lens is one of the best I found for this price bracket although the slow frame rate is disappointing. Unlike with older budget security cameras, this one boasts an i/r cut filter which when not needed removes the night time infrared filter to ensure good colour fidelity daytime images. It supports two-way audio which means it serves well as a general-purpose communications Monitor.

Like most rivals, this camera has motion detection but unlike most in this range also offers object tracking. The lack of audio in/out ports means external hardware cannot be used to improve the rather feeble audio quality. It offers full integration with the Amazon Alexa and Google home ecosystems which allow for voice control of the camera with the option to view camera streams on selected video devices.

The camera has the option to save video and audio within the app as well as to the SD card or to an optional cloud connection. If you use an SD card (none is provided) make sure you use a Class 10 or better card – the card must be able to cope with the high-speed data stream from the camera otherwise the results will be jittery and poor. A card between 8 and 64GB can be used.

This is a high-quality security camera capable of excellent results. The £39.99 price is fantastic for the features on offer and allows me to overlook the very few shortcomings.

kucoal LED Rechargeable Head Torch Set

This headlamp twin pack from kucoal has a premium feel and build quality that the rivals lack and which belies the bargain price but is it really any good?

In the small and distinctly downmarket box were just the headbands and two charging cables. No user guide was included although all the information needed is printed on the box although it is rather difficult to make it out. It is a pity that no storage case was included, but for the price that is understandable.

Each headlight has a robust elasticated headband with an adjustable buckle and in the centre the light unit itself, which is quite chunky and feels well made and built to last. Facing forward are three LEDs, a large central one for the main white light with smaller Red LEDs on either side. On top is the single easy to feel control button. The main light unit can be angled downwards in three click stopped stages. There is also a catch that allows the front section to pivot forwards 90 degrees to give access to the battery compartment for charging.

Operating the light is simple enough. Long press the button to turn it on – the last operating mode will be remembered – and long press again to switch from white to red light or vice versa. Short pressing scrolls through the lighting options: three brightness levels and flashing in white, steady on, slow flashing and long flashing in red. Fast click again to switch off in either mode.

The 180 Lumen flashlight is good and bright, and distinctly more powerful than would be expected from such a compact unit. The light is rechargeable with a built-in 1500 mAh battery accessible through the folding front panel of the light. I was pleased to see that an up to date USB-C port has been used for this. One charge should give between 4 and 12 hours of use depending on the operating mode selected.

This is a high quality, rugged, and robust professional-level piece of kit well suited to outdoor sports, caving, biking, and other high impact activities as well as for fishing, cycling, and other less intense pursuits. As a runner myself I would find it perfect for evening or night runs if I ever start them up again. I would have been quite happy to pay the asking price of £14.99 for just one of these headlights and to receive two is a bargain indeed.

VWRHar 4K Bidirectional HDMI Splitter/Switch

This deceptively simple little device allows one screen to be shared by two source devices or one source device to switch between two screens. In my tests, I used it two switch my Roku box from one monitor to another and to switch between the Roku Box and a PC on a single monitor. It will work with any HDMI enabled device and supports replay rates of up to 4K@60Hz. No power supply is needed, this is an entirely stand-alone device.

In the tiny branded packing box are just the switch device itself and a simple user guide. No cables or other items are included. The switch box itself is made from metal with two HD ports on one side and one on the other. On top is the switching button which is physical with good positive action with LEDs next to it to confirm the selection.

It could not be simpler to use. Once everything is connected up just press the button to switch between monitors or source devices depending on how it is configured. There is nothing to go wrong, nothing to adjust, it just plugs in and works. Remember this is a switch rather than a true splitter and you cannot use the two connected screens simultaneously.

The switcher will support 4k source devices up to 4K x 2K @60Hz and a range of other resolutions and file types including Blu-ray, DVD24/50/60fps/HD-DVD/xvYcc at 480i, 576i, 720i, 720p, 1080i, 1080p, and 2160p. Audio formats supported include LPCM7.1, Dolby-AC3, DTS, DSD, Dolby-TrueHD, and DTS-HD Master Audio.

A user guide is included but most users will not need it, this is a true plug ‘n play device and should work straight from the box with almost any commonly found video or audio device. If it supports HDMI then it should work with this.

In all my tests it worked fine with no lag or frame drops and since this is essentially a simple switch there is no reason to expect any. There is a slight delay when switching sources, as to be expected, and a slight delay when reframing the display on one monitor which suspect is down to the monitor I used

There are more expensive rivals available that look better and offer remote control, but if all you want is a basic plug and forget switcher then you will have to go a long way to find a better one than this for the £8.79 price.

RØDE Microphones MagClip GO

You do not physically get much for your £15 but yet it is one of the most useful add-ons I have for my video recording work. This little set allows you to conceal the rather bulky RØDE Go transmitter and microphone combo under clothing when recording audio.

In the box is just the metal clip and magnet set with no user guide included or needed. The ‎RØDE logo is on the clip and the magnet is plain with a matt black finish. Build quality is excellent, as to be expected from RØDE and so it should be for the price and the simple nature of the product.

The RØDE Wireless GO is a wireless microphone set consisting of a transmitter with a built-in microphone that clips to your clothing or any convenient object and a receiver unit that attaches to the camera cold shoe mount. Although small in size the transmitter unit with the prominent RØDE logo is still very noticeable when in position on close or medium distance shots. This set allows the receiver to be positioned inside the clothing with just the small and discreet magnet on the outside.

To use simply attach the metal clip, which has the RØDE logo on it, to the plastic clip of the transmitter. Once in place, it can be left there permanently as the plastic clip functions as normal with it in place. Position the transmitter inside the top layer of clothing with the microphone pointing up and towards the mouth and then place the magnet on the outside of the clothing in line with the clip to secure it in place. I have had no problems with it falling off or working loose and can it seems secure and stable when walking or running.

There are no problems with the product, it works well and as described. Although £15 is not much money and one level well worth it for the functionality it offers, I feel this should really be part of the microphone set. I would suggest that the next version be supplied with a built-in metal clip as standard and the magnet included in the box.

BoYata Adjustable Laptop Stand

This well designed and compact sized Z style laptop stand from BoYata is not inexpensive at £29.99, but it is always worth paying a bit more for premium quality. Made from premium gauge Aluminium alloy it should give stylish support to any laptop between 7 to 14 inches., especially Macs, with which the silver brushed metal finish complements. This is the smaller and lighter brother of other laptops stands in the BoYata range and is better suited to smaller sized laptops and tablets.

In the box is just the laptop stand itself with nothing else needed or included. Made from aluminium alloy with silicone anti-slip protective pads on the base and supporting plate along with retaining lugs on the front, the stand looks and feels like a quality piece of kit. The joints are stiff and hard to set, as they should be, but move smooth and silkily and once in position do not slip, wobble, or feel like they will ever need tightening. Should the joints loosen over time, and there is no indication that they will, I can see no way of tightening them. The base is well weighted and even when the laptop is at full elevation it feels stable and secure.

Using it is obvious and intuitive, the only point to mention is to be sure to open and adjust the stand from the centre to avoid putting undue strain or skewing to any single joint. No adjusting Allen key is provided, unlike with some stands, and there are no slots to fit it to but with this lighter weight stand this should not be necessary.

Priced as it is, this is not a cheap item, but it has a build quality and premier feel that the cheaper rivals certainly lack. I would have liked to have received a soft carry bag to protect other items when carried together, but that is no deal-breaker.

This is a quality piece of kit with a high end feel to it and will be a fine addition to your home office.

Logitech MX Keys Illuminated Wireless Keyboard

When my old wireless keyboard packed in and I discovered it was no longer available I needed to look around for another. By this time I had also acquired an M1 Mac Mini and a Logitech MX Master 3 For Mac wireless mouse and so it seemed to make sense to look for a compatible wireless keyboard to go with it. The MX Master mouse works just as well on my Windows 10 PC and so it made sense to find a keyboard that worked equally well on my Mac. The MX Keys is by no means the cheapest option available and cost nearly three times the price of my old backlit wireless keyboard with at first sight few advantages. I bought it for £76 but the prices fluctuate wildly and at the time of writing is priced at £95.24 on Amazon.

In the box is the keyboard itself, the dongle, a USB-C charging cable and a large amount of useless na dirrelevant paperwork.

The MX Keys can connect to up to three computers and can do so either using Bluetooth or with the included 2.4Ghz dongle. I decided to use the dongle to connect to my PC and Bluetooth to the Mac. Switching between them is simple using the three dedicated selection keys, just a touch instantly and seamlessly changes from one computer to another each with separate custom keyboard configurations using the excellent Logitech control software. The MX Keys can be used with either Windows or Mac and has dual markings on some keys to allow for this. Setup on the surface is easy enough but I had to struggle a bit to pair it to my Mac but since then it has been entirely trouble-free and connects automatically on startup or when using the keyboard selector. There was no trouble at all when setting up the dongle connection to my PC.

The keyboard is battery powered with a built-in Lithium Polymer cell charged using the USB-C port with a status LED to confirm charging and for low battery alerts. The keyboard can be used perfectly normally when charging if needed. It takes a couple of hours to charge it and one charge should give up to ten days or regular use with the backlight on.

The keyboard is very nice to use with good positive action and very decent key travel. There are audible and visual alerts for caps and numbers lock and for low battery status. There are no rear legs to change the keyboard angle but this is perhaps no bad thing as there is nothing there to break with the slight address angle produced directly from the rear lip of the keyboard base. Perhaps the most interesting feature is the proximity sensor built into the keyboard which turns the backlighting on when it detects a finger about a centimetre away from the keyboard and off again when typing finishes. This works well and has given me no trouble whatsoever which is just as well as I find the keyboard markings themselves to be rather dim and hard to see in low light. The backlighting can be switched off through the Logitech software.

In short, I have to say the keyboard has worked flawlessly every time for me with great battery life and is probably the best wireless keyboard I have used. However, it is not without issues, There is a large amount of paperwork included but no actual user guide and this has to be downloaded via the rather hard to navigate Logitech website. More importantly, there is nowhere on the keyboard itself to store the small and easily lost dongle, a nuisance for those who connect only using Bluetooth.

This is a great keyboard although entirely free of issues, that works well but is expensive with cheaper rivals available.

The Good
Good Build Quality
Good Typing Experience
Supports 3 Computers
Bluetooth or Wireless Connection
Windows/Mac Compatible
Good Configuration Software
Excellent Backlighting
Integrates With Other Logitech Products

The Bad
Poor Documentation
Hard to Use Without Backlighting
No Dongle Storage Option
Expensive
