Product review (5 stars): Mine are at least 7 years old and still like new. I like the color option as black ...
I just bought a set of these for my daughter's new home.  Mine are at least 7 years old and still like new.  I like the color option as black is what I wanted.  They are a breeze to keep clean, wipe easily in place OR just lay in the top tray of the dishwasher and they come out like new.  The main thing is that they really do completely stop "stuff" from dropping down between the stove and your cabinets.  I cook a lot and my husband cooks too, bless him, so you can imagine what that might mean if I didn't have these seals. Considering the nominal cost these are one of life's real bargains.
