Summary: The keyboard lags terribley. It will barely work if you have it too close to the wireless reciever. The Mouse lags terribley. You absolutely cannot play computer games with this or you will want to break your computer. Maybe I just got a bad one though....other than that, everything else is fine.
Summary: Works as intended, but Logitech says in manuals to expect 4 months of battery life from mouse. I'v owned product for about 6 months and changed the mouse batteries 3 times so far, less than 2 months per change. Not very "green". Listen, I can afford the batteries, but--call me deluded--I expect more. Logitech has work to do ...
Summary: I bought the unit to control a computer connected to a TV set. The supported range is quite short-- maybe 10 to 15 feet. I have seen other units with much longer range. Other than that, it works fine.
Summary: I am a medical transcriptionist. Often I have to hit the keys (hard) because a letter doesn't type or the space bar fails to work the first time. It is a nice keyboard for someone who doesn't type very much but now I am faced with buying a new (and most likely more expensive) keyboard that has a better touch and response time. In the space of several hours this gets VERY annoying and it makes me want to scream.
Summary: The mouse is exceptional. The keyboard however is so-so If you use funtional keys F1-F10 forget about this keyboard. Those keys are very small and hardly usable. Also the "Enter" key is smaller than on most other keyboards. I miss it quite often after some time working with a normal keyboard.
