I cannot guarantee 100% compatibility with all devices; however, I've successfully tested it with a number of Win 10/11 and Android devices. Screen and keyboard seem to work for all. Touchpad worked with some Android devices, but appeared to work with all of the Win 10/11 devices I tried it with.
No refunds for being "incompatible" or "touchpad doesn't work"... It does, it just might be that your specific device doesn't recognize it. Do your research first before buying.
In my experience it's been a great premium feeling lap dock. I've tried it with a galaxy note 9, an AMD 6800U handheld pc w/Win 11, and an old Dell Cherry trail Win10 tablet. All worked with the screen, touchpad, and keyboard. I can't remember what didn't work with the touchpad, but it was some older/obscure Android devices and old version Windows 10 devices... I also tried it with a surface Duo. It worked, but was "wonky".
