I needed a backlit keyboard with clear keys. It's just the opposite! Gradually turn on and off backlit keys with distracting colors that are useless to look at. I am not a professional blind machinist and never will be, I NEED TO SEE THE IMPRINT ON THE KEYS! Even in bright daylight, the letters are barely visible. The mouse is too sensitive on the left side and consumes too much power. If I don't turn off the mouse, it's DEAD the next morning. I've never had this experience with other pointing devices. Also, the mini USB port for charging the mouse is deeply embedded in the mouse body and is very difficult to insert.
