The mouse is great, very sensitive. It's nice to use in Photoshop. The five programable buttons work well and are easy to program.The keyboard works fine. I like the zoom slide and calculator button. This keyboard has more features than I am likely to use, but I am a gadget junkie.The only things I have a beef about are lack of a light on the caps lock key, (I often hunt and peck and I sometimes type all caps). I realize a cap lock indicator would be a battery drain. Occasionaly, a window pops up to tell me the mouse is out of range or low on power. When I check the mouse application, all is well. My last complaint is a matter of taste... I am tired of silver plastic. It's the fake woodgrain of the new century. It's about as tasteful as Courtney Love at the Pope's ordination.The keys are worse than the silver board. They are a translucent grey. Roboturd grey? I am happy with the functionality of this keyboard but it makes me think of the ugly kid down the street.
