Phil, glad to hear this as this has been a problem for me is it possible you can upgrade our unit i purchased for the YSS?, I cant see how these covers will make the buttons lighter to press though, one of the big problems i have with ours is the buttons are so stiff it shifts the unit off target, also the alarm difference between "laser fail" and its reading a leg successfully are to similar, if they were wildly different this would prevent having to look at the screen as i have found a number of times i have take the fail sound as a leg reading, thanks
