I got this keyboard specifically for use with the Raspberry Pi 4 and it works GREAT. All I had to do to use it with the Pi was literally all I had to do was plug in the dongle (located in the back plate of the battery), flip the switch to the "ON" position, and boom, it worked automatically. After reading the other review here I was a little concerned that it would require some tweaking or some quirk to make everything work, but for me it's not. Here are a few things I love about this compact wireless keyboard and touchpad combo: 1. Ergonomic shape - feels good in the hand, matte black plastic feels nice. Overall, its shape is very comfortable and easy to use, your hands will fit naturally, and the touchpad is easy to reach from the keyboard.2. The touchpad is great - it supports one, two and three finger gestures, tap to click and sensitivity adjustment. In addition, it has a nice texture that allows for smooth mouse movements. Pleasantly surprised here.3. The keyboard is 99% identical to the full-size keyboard without ten keys - all the function keys, control keys, alternate keys, etc. are all there, just like on a regular keyboard.4. Keyboard keys are responsive without ghosting5. Battery life is good - I had it for a few days and used it without charging during that time.6. The RGB backlight is adjustable - you can adjust both color and brightness, or turn it off altogether. To change the RGB backlight: Hold down the Fn key and slide one finger across the bottom of the touchpad from left to right. The BFTECH Mini Wireless Keyboard is on the cheaper end of the spectrum compared to other similar products, so I wasn't expecting outstanding performance when I received it. But that's exactly what I got. Great value for money for a functional, well-designed, Raspberry Pi compatible mini wireless mini keyboard with plug and play functionality. Five stars are everywhere.
