Product review (4 stars): Grates are NOT too high! They are perfect!
UPDATE: I've had this cooktop for over three years now. I've downgraded it from 5 to 4 stars. This is why: 1. Middle burner ignighter broke after a few months, I now have to light it by hand or pay to have the whole cooktop removed and fixed. 2. The cooktop NEVER looks clean and gets dirty easily. 3. The burners are unsealed - which is probably what caused the middle burner to stop working. 4. The griddle is useless. It holds about the same amount as a regular pan. Other than that I actually do love it.

I almost didn't buy this cooktop because of all the reviews about the grates being too high. I believe people who were used to cooking on electric cooktops don't understand that gas is very different to cook with. The grates are fine. I get tons of compliments on this cooktop, and I love to cook with it. My husband installed the cooktop - it went in easily and works great. The only down side is that it's kind of a beast to keep looking "clean". I love the look of stainless but one touch and you'll leave a finger print.
