Was looking at buying some decent wireless mini keyboard/trackpad for my MK802 Android stick, and found some good reviews about Lenovo N5902 (one model higher than N5901).
I had a 10% discount code but was having troubles entering it, so contacted Lenovo to find out, and the lady offered me 15% discount code.
THE CODE MAY WORK FOR THE OTHER LENOVO ACCESSORIES AS WELL. PLEASE TRY FOR YOURSELF.
@ batrarobin, the track mouse on N5902 is to small, you have to slide couple of times to move your cursor from corner to corner.
The older and cheaper model N5901 - with trackball is easier to navigate. But! the Enter button is well hidden on the right side + no backlit
It's up to you :)
