Recently purchased this to accompany my new LCD/LED Smart TV. Found it easy to install and use. Performance Easy to set up and use. Mouse seems less smooth than the one used on my PC, but that could be because of the smart tv rather than the quality of the wireless mouse. Durability I've not had this very long, so am basing my rating on the experience I've had with previous Microsoft products. Design It has everything I need for using it with my television. Nothing fancy, though. Comfort Since I'm using it for a shorter period of time with my television, it's fine. However, if I were to use this with my PC, I would want a keyboard more ergo-dynamic because I'd be using it longer.
