Product review (5 stars): Silicone Better Idea for Tight Spaces
Good price for such a valuable product.  My appliances fits very tightly between (1/4-1/8 inch to sometimes no space at all) granite counters and would be near impossible to move.  Thus the flexibility and ability to cut to size of silicone is a great advantage.  Silicone also lies flat on counter so should stop any crumbs or spills from getting between counter and appliances.

Delivery and packaging excellent.  I plan to wash by hand rather than in dishwasher, which instructions say is okay, since hand wash would be easy and ensure that dishwasher heat does not warp these.  Plan to by another set for one more appliance that I have.
