Summary: Let me start by saying I've only been using this unit for 10 months. I was a bit concerned about using induction since I had used gas for the last 20 years - I was nervous about switching. I shouldn't have been. The induction is a marvelous, energy efficient and flexible cooktop. It will boil a gallon of water in under 8 minutes and melt butter without burning it. I've sautéed, fried, braised, boiled, simmered and warmed; all without any trouble.
Summary: We bought this as part of a major kitchen remodel. In general, we've been very happy. We love having more countertop available. The reputation of induction is well documented. Couple of issues: with only one large burner, it is tough to have more than one large skillet or pan going at once. I wanted to love the bridge element, but when I put the cast iron griddle to make pancakes, the area in the middle (the bridge) shows serious temperature differential.
Summary: Perhaps not all induction cooktops are riddled with problems, but this kitchenAid induction cooktop certainly has been. After problems with my first purchase and 4 months of trying to get it repaired, we were given a new cooktop which also had problems and were without it for another couple months. KitchenAid finally admitted to having mis-wired some of the cooktops. My cooktop still does not work properly, and it seems as though I'm just stuck with it.
Summary: I have the 30" KA induction cooktop. Induction itself is wonderful - responsive temp control, easy to clean, fast heating - but KA is extra noisy. As someone else mentioned, it clicks rhythmically at all temps lower than 6 as the magnets cycle on and off. Other brands apparently use a solid state method to modulate the heat, so no clicking. If you run the hood, if the cooking sounds get louder, if you play music, all this can drown out the clicking somewhat.
Summary: This cooktop replaced a 25 year old GE Induction cooktop. I've always been one to embrace new technology and I've been cooking for over 40 years. I've used gas (yuk) electric and induction. Induction is the only way to go. Fast and much cooler for those of us living in the warmer parts of the U.S. where we thrive on A/C. This doesn't heat up the kitchen the way conventional cooktops do. I've read so many reviews, most of which aren't kind to induction.
Summary: This cooktop has totally met our expectations. We went from natural gas to induction with this kitchen and have found it to be very accommodating and flexible. Our concern was that the heat would not allow for a slow simmer or melting butter. The fears were not based in reality. It is so easy to do both and the unit will boil three quarts of water in about 3 minutes. The only drawback on the unit is that it won't accept a small pan (smaller than a 4" bottom).
Summary: We started having problems with this unit 2 weeks after installation with an F47 error code. Parts were backordered for several weeks. Once installed, they didn't fix the problem. The technician had to remove the unit and take it back to his shop to work on it. Now there is a clicking sound that happens at settings below 5. It gets louder when set on simmer. KitchenAid claims it is normal operation and will do nothing else to resolve the issue.

Summary: I would prefer to have a gas cooktop, but in my new location this induction cooktop is the better option. I don't have the ability to vent exterior. This cooktop does produce less heat than traditional gas or electric. Heats up fast and is warm to touch within minutes after you are done. Can boil a big pot of water in just a few minutes--extremely energy efficient. Easy to clean vs. gas. The one thing I don't care for is the alarm when you remove a pan from the burner.
