I haven't tried this keyboard but I've tried several other stick-on types and the stick-on labels always fell off easily. And if you try to take them off to replace them with more stick-on labels, getting the keys really clean from that adhesive gunk is a project too.
I don't look at the keyboard much because I learned to touch-type at an early age. You could try learning that if you haven't already. I still do need to look at some keys though because computer keyboards are a bit different from what I learned, a thousand years ago.
Also, what they're promoting in the ad as an "ergonomic mouse" isn't very ergonomic. I've tried out some mice of this type and don't think they'd help much.
