Review on 🔍 Mini Wireless Keyboard with Touchpad & Backlit, Rechargeable Handheld Remote for PC, Raspberry Pi, Android TV Box, KODI, Windows 7/8/10 by Josh Sharp

I used this to eliminate the need for a big clunky keyboard in my retropie build for Raspberry Pi 3 (the battery compartment on the back) and it closed himself immediately. I checked the keyboard functions and it works like a charm. I haven't used it as a controller so I can't speak to our qualifications. It seems a little impractical for this type of use, but you'll have to look at those who have actually used the feature to get a real estimate.
