Product does what was described.  Doesn't warp or roll up when you roll over it as thinner floor protectors do.  Is a harder, rigid material, which I like.   I have light wood floors which didn't want to get scratched.  I do wish I had measured the opening under my desk better because it could be a little wider, which is why I gave it a 4, not 5- but pleased with the purchase.

Cons: .
