Product review (5 stars): Better than any cooktop you ever tried!
My wife and I bought this for our new home even though after quite a bit of hesitation, as this technology is not very popular, and we did not know anybody that had used it before. We new that most of our pots and pans would not work with it, but that was not much of a concern as we wanted to upgrade our cooking ware anyway.

Sure enough, the first try of our new cook top was a big surprise. But the good way. The performance simply blew us away. We have never experienced anything that comes even close in terms of reaction speed, ease of use, and sheer power.

Pros:
* Extremely powerful. Boiling water, making fish/meat stock, making pasta become easy and enjoyable.
* Reaction is instant. No need to wait for temperature to go up or down. The second you touch the control panel, the temperature reacts.
* Low heat setting can make long simmering more precise.
* More energy efficient then gas or electric.
* Very little heat loss through the air. As a result, the ambiance temperature never gets too hot even when I have all five eyes on, making fish stock.
* Timer is a useful plus.

Cons:
* Many types of cookware, including aluminum and most stainless steel does not work (use a magnet if you want to check whether yours does, only if it's magnetic it works).
* There is a humming noise, not very loud, but noticeable.
* It is not the best for Chinese stir fry because only the bottom of the pot/wok is in contact with the heat source, and the side of the wok may not be as hot as the bottom. Nevertheless, I use it often for stir fry, and it is fine enough for me.
* Cannot grill.

Overall conclusion: Once you tried this everything will feel like Stone Age.

Added: After 2 years, we're still very happy w/ it. Note: 2 left eyes share one circuit, and 2 right ones share one. This means that the ones share the same circuit cannot be on H(igh) setting at the same time. One of them will automatically be downgraded to a lower setting (such as 7, or 8). We noticed something rather strange in such situation. The eye w/ lower setting seems to continue to burn at H level, on and off. It seems that the two eyes are constantly changing from H to lower power then back to H in an alternating pattern. It can be a problem if 1) you need to use H setting, 2)use both eyes at the same time, and 3)want to control the power precisely for cooking. Or you will have to choose another brand that gives each eye its own power circuit.
