Product review (5 stars): Wonderful Product
This is a truly outstanding cooktop.  I have cooked with electric, gas, and now magnetic induction, and magnetic induction has been the most enjoyable experience by far.  It's really not even close.  Prior to hooking this cooktop up I timed how long it took my (previous) gas oven to cook 96 ounces of water in an uncovered pot: 11 minutes and 30 seconds.  When I hooked up this cooktop and tried the same amount of water in the same pot, it took 4 minutes and 45 seconds to bring it to a rolling boil. It is amazing how fast this thing cooks.  I can boil water in a small saucepan in under 2 minutes.

And not only does it heat things up amazingly fast, but it also allows one to bring the temperature way down to do things like delicately melting chocolate.

Another huge plus about this cooktop is that the hobs ("hobs" is a more official word for "burner") are diagonal instead of the typical way they are laid out in strips of two each. This was the main reason I narrowed down to this particular induction cooktop (other than it being made by Miele, a company that makes ultra-superb products).  By placing the hobs diagonally it opens up a lot more space for placing cookware. I've had all four hobs used up by relatively large cookware, without any of the pieces bumping into each other.  This was also the reason I went with the 30-inch model instead of the 36-inch (well, that and the fact I would've had to do some cabinet rearranging to get the 36-inch model into place). Simply put, with the diagonal layout I didn't feel the need for a fifth hob.

It's a breeze to clean, you can associate a timer with each hob to control when each shuts off (a great feature for, say, pressure cooking), the range of cooking temperatures is very wide, and it's great to know that when I hit "7" for a temperature that I get a rolling simmer and when hitting "6" I get a lower simmer--every single time.  Also, provided you have a decent set of cookware (and likely even if you don't), say goodbye to hot handles: induction cooktops are so efficient that unless using cookware laden with very cheap handles (and I bet even cheap handles wouldn't make a difference) your handles won't heat up.  We've been cooking with this cooktop for 6 months now and we have yet to experience a warm handle.  I'll note here for people unfamiliar with induction cooking that the cooktop doesn't actually use heat to heat up the pan.  Instead, it uses magnetic induction, which causes the cookware to heat up.  Consequently, you need magnetic cookware in order for this to work--such as magnetic stainless steel or cast iron.

One thing I should note is that I specifically bought a very expensive set of cookware to use with this cooktop: the Demeyere Atlantis collection.  I mention this only because I have read that cheaper cookware may emit some buzzing or even popping when used with induction cooktops.  The Demeyere cookware does not emit any noises, and I'd expect that because it really was designed for induction--though also perfectly capable of cooking wonderfully with gas or electric.  So, if you're going to buy this kind of cooktop, I suggest going all the way and getting some quality cookware.  I should also note that the Demeyere Atlantis cookware is incredible cookware...it is leagues above the cookware we had prior to getting it.  You should see how it cleans!

This is a wonderful, well designed product and I give it 5-plus stars.  My wife and I love cooking with it and cooking is noticeably more enjoyable since we've had it. If you can afford to buy a Miele product you very likely won't be disappointed.
