Key strokes are perfect not too long and not too short. Though a little louder then say your average run of the mill default keyboard its got a nice sound that lets you know you have hit the key. The build quality is excellent and feels as though i could throw it and it wouldn't break. Though there are only 3 media buttons (sound up/down and mute) thats all any real computer needs. And the back light is perfect. in pitch black conditions its more then bright enough to see every key crystal clear. Even in fully lit conditions the back light is bright enough to make the keys seen. My friend has a G15, which i use all the time, and i prefer this keyboard. Better key feel, smaller more convinient and 1/2 the cost. Its perfect.
