A4 Tech NB-30D USB

I found it most helpful when I was recently very ill and unable to move from my bed after turning on my computer and doing everything else from where I lay.

The USB cable sometimes got in the way, it would be better if that was wireless too.

Good value, innovative product, easy installation

accurate positioning all the time

Double clicking left and right keys does not always work 1st time

Easy to install and very easy to use, the best mouse I've ever used.

none

Saves not having batteries, button for double clicking saves time, looks good.

None.
