It does exactly what it needs to do! Easily trimmable if it is too big or you just don't have the energy to reposition everything *again* so the pad is completely hidden :) I would give it a 4.5 if I could, but I gave it a 4 because of the chemical odor that it has, which is obviously expected from its manufacturing and packaging. If it was miraculously odor free, it would earn 5 stars!
