Product review (4 stars): Great customer service!
We ordered a set of these covers and received them all dented up from being shipped in a padded envelope.  This is more on amazon than the Range Kleen Company.  They should have been packed in a box for shipping as all of the damage was clearly from shipping.  We contacted the seller immediately and they were excellent.  They responded right away by email and sent out a new set immediately.  The new set was dent free and works perfectly on our stove top.  The fun cow print works well on our black stove, but would look good on a white stove as well.  The covers fit the burners perfectly.  They wipe off easily to clean.  These are thin metal covers, but we expect them to last a good while unless of course there is human error of not removing them from the burner when we turn it on (which is why we needed to replace our old ones).  I would not expect sitting anything heavy on these would do them any good either as they will bend easily from the weight. But for the pure purpose of having a neat, clean stove top- these work very well.
