Product review (5 stars): Much better than metal
Really happy with these so far.  I got sick of buying the metal ones, when I could find them, that would inevitably bend or warp and then it was always sticking up here or there.  These obviously install in a snap, you just lay it down. So far no issues with heat and wipe clean.  They lay very flat and stay right where they're placed.  Much happier with these than metal and the clear pretty much goes with anything.
