Product review (5 stars): Necessary to protect stove!
These were a lifesaver for our stove grates.  We have a DCS stove and the rubber feet wore off but we couldn't get replacements from the company.  We found these and they work great to prevent scratching of the stainless stove surface.  The price is so reasonable that we bought extra to keep around in case these wear out.  So far, however, they have held up great!
