overall , its a good value for a wireless keyboard\/mouse combo and I be happy with it . I have have it for about 6 month now and it work nearly as well as it do new . it seem the ball socket have build up some dirt , but I can not figure out a way to clean it out . it be pretty comfortable . it work well for all-in-one control of a htpc . it be very convenient for that purpose , but you would not want to use this for gaming or write a paper . it be not very responsive or intuitive . not every key be present . it should have backlighting . fast movement = jerky motion . battery life range from a couple of day to a couple of week . battery will drain if you leave it on . consider invest in a good battery charger and rechargeable aaa .
