Product review (5 stars): Worked for DCS cooktop & the price is right!
These worked fine with our DCS cooktop.  After 9 years, we had lost 9 out of 12 rubber feet.  Most of these new feet went in really tight -- a combination of twisting and pushing was required to get them in.  Strangely, one went in really easy and falls out, but that's a problem with the grate, not the rubber feet.
