Product review (2 stars): " That made this a really bad purchasing mistake
Did not fit my old Thermador stovetop--was too small.  Could not get help from Thermador in identifying the correct part.  The seller (Gatzies) would not refund my money without charging a 50% "restocking fee."  That made this a really bad purchasing mistake.  Especially since it probably took all of 5 minutes for the seller to open the box, take the product--in its original packaging--out and put it back on the shelf. I continue to search for the right part, but will not do business with that seller again.
