This is perfect as it slides between stove top and our stone counter tops preventing crumbs. Easy to take out and clean off as well. Nice hard plastic

The only problem is that they are not long enough.  We have a inset range in a island counter top.  These are the longest ones I could find, and they are still a inch or two short for what I need.
