Nice rock solid keyboard, aluminium upper plate and plastic shell underneath delivered on time in a nice cardboard box with proper protection inside. Keyboard, key puller, USB-C cable and instruction leaflet. Good tactile feedback from the RK brown keys, and silent enough not to be bothering folks nearby. Keys seem a little cramped at first but one gets used to them quickly. ANSI US layout - nice ! NKRO, lighting effects, multimedia keys... all working well under linux and android Cabled (USB) connection is a no brainer, just need to remember to switch off the BT underneath the keyboard. The cable is rather long and thin, which makes it flexible - a bit too thin as it does not stay in the channels under the keyboard if using it in your lap, and probably a bit too long if using it on your desk. No problem since it s detachable and can be replaced by a different one if needed. Recognized as an apple keyboard under linux (05ac:024f), with no Fn key. I had an issue initially with the F1-F12 keys which would act on screen or keyboard backlight and some others - solved by setting the fnmode parameter (thank you google :)). . ; As root, use the following command to set the fnmode parameter to 0 (ot add it in /etc/: echo 0 > /sys/module/hid_apple/parameters/fnmode Contrary to what was stated in the description, it does not have 3, but 5 possible BT connections, and they work well (smartphone/tablet). Documentation leaflet is small but sufficient. Haven't found any software for it (G87 does not exits on the Royal Kludge web site), but even if there was one I suppose it would be for Windows rather than for linux, so no use for me. Still would be nice if there was something for linux users. In short - very happy with my purchase at 43€ (Hah ! even the euro key works :)), nice solid keyboard with a decent feel.

Came well protected in a cardboard box with foam filling, shipped rather quickly (from Germany to France). Works OK when placed on the woodstove, even spinning rather quickly, but fan is slightly wobbly and not moving much air. Rather silent when placed on a flat surface. After careful bending of the blades the wobbling was mostly eliminated. May need to experiment with different angles to see if the airflow can be improved a bit - the little motor apears to have sufficient power. In short, interesting little device with its peltier element and small motor, but not quite as effective in mixing the air in the room as I had hoped.

Nice little no frills QWERTY US keyboard, does what it says. Easy to type on if you're used to laptop chiclet keys, some light scratchyness which may well disappear with use. 12 screws underneath for easy opening, all plastic case with a little flex if you apply sufficient force, but very stable on the desk thanks to the small rubber feet. Caps and Num Lock LEDs. In the box: Keyboard (usb cable attached), small leaflet in chinese. Recognized without problems on my linux system: [ 32.291589] usb 2-1.2.1: new low-speed USB device number 14 using xhci_hcd [ 32.449447] usb 2-1.2.1: New USB device found, idVendor=1a2c, idProduct=2124, bcdDevice= 1.10 [ 32.449452] usb 2-1.2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 32.449456] usb 2-1.2.1: Product: USB Keyboard [ 32.449459] usb 2-1.2.1: Manufacturer: SEM [ 32.459176] input: SEM USB Keyboard as /devices/pci0000:00/0000:00:14.0/usb2/2-1/2-1.2/2-1.2.1/2-1.2.1:1.0/0003:1A2C:2124.000A/input/input39 [ 32.516018] hid-generic 0003:1A2C:2124.000A: input,hidraw3: USB HID v1.10 Keyboard [SEM USB Keyboard] on usb-0000:00:14.0-1.2.1/input0 [ 32.518575] input: SEM USB Keyboard Consumer Control as /devices/pci0000:00/0000:00:14.0/usb2/2-1/2-1.2/2-1.2.1/2-1.2.1:1.1/0003:1A2C:2124.000B/input/input40 [ 32.576183] input: SEM USB Keyboard System Control as /devices/pci0000:00/0000:00:14.0/usb2/2-1/2-1.2/2-1.2.1/2-1.2.1:1.1/0003:1A2C:2124.000B/input/input41 [ 32.576530] hid-generic 0003:1A2C:2124.000B: input,hidraw4: USB HID v1.10 Device [SEM USB Keyboard] on usb-0000:00:14.0-1.2.1/input1 Despite registering as a Keyboard, Consumer and System Control device, it has no media or other non-keyboard functions that I can see. That was expected, though it would have been a nice surprise to find some key combination for volume control and play/pause/prev/next. All in all, recommended if you're looking for a small space saving keyboard, or a spare for your raspberry.

Shipping took a littwo weeks rather than the expected 1-week, but with the UK not being in the EU any longer, maybe that will be the new normal. Time will tell. Nicely packaged, each board (I ordered 2) was in an antistatic bag inside a bubble wrap bag inside a manila envelope, the individual envelopes placed together inside the usual heavy plastic bag. Anyway, as described in other reviews these are quite nice little boards, delivered with pin headers and a little cable+plug for connecting a LiPo battery. Charger is set to charge quite fast, at about 400mA, and the board gets quite hot to the touch in the area of the charger chip. Arduino development works well, including the examples (on my linux box, I had to remove blanks from some directory names in the library so they would compile); platformio as well. The color display is small (160x128) but definitely nice for displaying status messages, a meter, or some sensor value. Price was 16.92€ for two boards, shipped from the EU warehouse (UK in fact) to France. In short - happy customer, can recommend this board if you're looking for an ESP32 with a small display.

Very lightweight, minus one star for a worrying rattle inside the case (could not open to verify since it seems to be ultrasound welded), however the supply works as advertized without any problems to power my raspberry pi server, which was complaining about low voltage with the previous supply (a phone charger). Happy customer, would buy again.

Ordered by mistake expecting it to come with the SX1302 LoRa concentrator. As is, the boards are well made but I have no use for them.

Delivery took a bit longer than expected (Ordered Oct 22, stated "1 week delivery", shipped 23 but arrived Nov 6, a week later than expected). Haven't installed it for now as the original one works just fine - problem was with the high pressure fuel pump (THP engine).

Ordered Sat 17/10, arrived Mon 26/10, not too bad for a promised 1-week delivery (sent from Germany rather than UK). Solid metal device with a quality feel, good transfer speed from both the PC using the regular USB connector, and the phone using the USB-C connector. Perfect for taking a few videos on a plane trip for example. I was planning to also copy files from Android to the usb key for backup and transfer purposes, but that probably needs an app - haven't figured a way to directly copy photos to the usb key yet. All in all, nice amount of storage in a handy format for a decent price. Recommended.

Very fast shipping, well protected in the original box plus foam padding plus two sealed bags. Product as expected - nice and fast. Not quite as heavy or bulky as I feared it to be (coming from an older Android 4.4 UMI Zero with a 5" display). Exported contacts via SD card from old phone storage and imported on the new one without problems (those folks syncing everything to their google account probably have it even easier). Had to cut down my SIM card as it takes a nano sim - simple enough after printing a template found on the web. All in all, quite happy with my purchase - thanks Banggood :-)

Simple and efficient. Used to control compressions on a Citroen DS3 THP155 engine with rather deeply inserted spark plugs, worked like a charm (no need to overtighten thanks to the rubber o-rings). A pushbutton releases the recorded pressure from the gauge for the next cylinder.

Exactly what I needed to fix my 20y old suspension lamp, whose sockets and cables had been rendered brittle over time by the heat from the original bulbs (20W halogen lamps). Happy camper !

Product as expected, however arrived with a corner of the facade broken off and the casing squashed due to insufficient packaging to absorb shipping and handling. No big issue given the intended use, but some additional bubble wrap would probably help.

Very decent product, delivered with USB cable, two semi-rigid extension cables, and open/short/load/through pieces. Firmware is reactive and relatively intuitive (though I still need to learn a lot about the RF jargon). Works well in conjunction with the PC app as well (tried on linux, NanoVNA_QT_GUI-x86_64.AppImage).

Device received is revision 8 (latest is rev 10 from aug 2019), comes preflashed with SoftRF release 1.0-rc7. Just add an 18650 battery (careful about polarity, clearly marked on the board), charge it over USB and you are ready to go. Interna WiFi access point allows configuring the firmware (password 12345678, connect to 192.168.1.1), notably enabling BT and NMEA output over Bluetooth to make it a perfect complement to xctrack, xcsoar and lk8000 glider software running on a tablet or smartphone. GPS is a uBlox neo-6m, not the very latest (there is another more expensive board sold with an 8m) but sufficient for my purposes. A useful addition is a BMP280 barometric pressure sensor on the I2C port (the firmware recognizes it at boot, just like bmp085, bme280, and mpl3115a2 - probably bmp180 as well). You can also add a small 0.96 inch OLED display, which will display the glider ID, protocol, and rx/tx counters. The firmware sources and other project files are available on https://github.com/lyusupov/SoftRF - looking forward to add some bells and whistles :-)

Nice flashlight, decent size (not too small), zoomable and very bright. Bought it essentially because it is rechargeable (micro usb). The tail button (a bit small, but workable) switches between front led high power, front led low power, cob led on, cob led flashing, off. Happy customer :-).

Extremely fast shipping from the UK depot to France, using the Colissimo shipping option - ordered on sunday, received on thursday ! A previous order of the same device using the default (free) delivery never showed up - tracking said 'returned to client' - and was reimbursed by banggood after 30 days. Very happy with the scope, very intuitive and reactive user interface and large screen. The device boots in a little less than 10 seconds. Accompanying mini-CD contains PDF manuals in perfect English and Chinese, as well as some Windows driver/application which I haven't played with since I'm running exclusively linux. Thanks Banggood !

Nice compact supply, delivered in due time (20 days from China). The flimsy carton was a little squashed but there is ample padding inside, no damage to the supply. Also in the box was a travel adapter for EU/french sockets, nice gesture but not necessary here since the cable provided with the unit already had a EU plug. A small booklet explains the use (in english). A small rattling was promptly fixed by tightening the two screws at the bottom which had come a bit loose during transport. Usage of the supply is straightforward: Turn on, set up voltage, shorten the outputs and set up current, then connect to your device. Setting up precise voltages or current limits, particularly for small values (ie, 3.6V/15mA), is a little fiddly since the coarse potentiometer is quite coarse, and the fine tuning potentiometer has a limited range. The unit has a fan, but I suppose it only turns on when needed, making it very quiet to operate. For 41 euros delivered it is definitely good value for hobby use.
