This is actually my first keyboard cover I've purchased so I don't have anything else to compare it to. But overall, it serves its function. One of my friends purchased one similar on Amazon but different company, and her's is much thicker and can't see back light on keyboard. The one I purchased is thin, which I like because I can still see keyboard light. The cover is nice and smooth, fits on keyboards correctly, and doesn't move around. Stays in place. The only reason I rated it a 4 out of 5, because little pieces of lint (i.e from either clothing, and my dog's hair), grips on the keyboard. It's not a deal breaker for me, but I just notice it because I use my computer for work everyday.
Serves it's function...
