Product review (5 stars): Good quality and easy to clean
I bought the Range Kleen 687 for my parents since the last two oven seems my parents bought warped over time, melted, or burned. The plastic seams were useless in less than a few weeks if you are not extremely careful. Fortunately, the Range Kleen does what it is supposed to do and prevents food from falling into the cracks between your oven and counter top. It is solid and has a bit of weight to it, so it does not unnecessarily lift, it is very easy to clean with a damp sponge, retains its shape in extreme heat, and seems to fit standard sized ovens. Don't even bother to waste your money on those plastic ones. This is all you need.
