We bought this 1) for induction enhancement over our old cooktop.  The issue was in the install, says fit guaranteed.  Nope, we took out a 30’ cooktop and set this in and it was smaller in measurement so it barely cover the cutout, made for a 30”.  When I called and saw In the instructions we have to buy a separate item for the fit.  Seriously!!!  That should have been said.  I feel that was very misleading and the person who answered was not helpful or nice.  I like the cooktop, little noisy with the magnets, but way more efficient so far
