Relaxing on the couch or giving a boardroom presentation? Roam up to 30 feet away and retain reliable wireless control of your computer.

I've been using this mouse for three weeks now and it's very good. I used it even on reflective surfaces without problem. The fourth button can be configured to execute custom command, but only one. I use it as AvPag, but can be any key or key combination. I recommend it.
