Its a great concept but i find that it gets in the way and ends up sitting next to my computer while i type like it is right now more often than it gets used on my keyboard like its meant to be used

Update so i deducted 1 star because i just notice that if you were to use this in the dark chances are you wont be seeing the letters on your keyboard so well since they arent cut out and even the backlit led feature on your laptop cant really help

Probably the best bang for your buck
