Positives:
Great Range with no issues controlling my laptop behind the TV form anywhere in my living room. Battery Life is excellent with easily a several weeks of use before needing to recharge.
The buttons feel solid with a nice click so you know you hit the key.
The sensitivity on the touch pad is just right.

No back light on the keyboard. (If you want a back light check out the upgraded Rii One i28. Same lay out but has a back light.)
