This is the ozupad air. It's a one-handed device (mobile mouse). It uses 2.4GHz wireless and is battery-powered. While the compatibility information states it supports up to Windows 7, it worked on Windows 10. I haven't confirmed its use on Windows 11. It is currently discontinued, and the manufacturer no longer offers repairs, so please refrain from purchasing if you are overly concerned about this. No claims or returns accepted. I will wrap it in bubble wrap and ship it in a box.
