Product review (4 stars): Much better price than local dealer.
Fits my new downdraft Jenn Air cook top exactly and at a much lower price than the installing dealer had quoted me.

Couple of design issues - The hobs are not outlined, so you really have to turn them on to make sure you know exactly where to place your cookware. Once the hobs are turned off, there's no indication that they're still hot (and they stay hot for quite a while). Could be a safety problem if you have young hands in your kitchen.
