Product review (5 stars): Just do it!
If you've been thinking about induction...stop it and just take the leap!  I went from a coil burner (I have used gas in the past) to this cooktop.  There's no turning back now!  This is the most amazing way to cook!  Responsive and quick doesn't begin to describe it.  The first meal I did with it and my new CIA cookware, I quickly realized that this was a whole new cooking experience.  The biggest 'problem' now is, relearning timing of prep/pre-heat...it's too fast, I can't keep up!  I now wonder why I had spent so much time and energy agonizing over the decision to go induction...you can even keep your gas, this is so much better!

Clean up is easy!  My second dinner, I had some boil over, so I lifted the pan, took a rag and wiped it up, put the pan back down and continued cooking.

I agree with the other reviewer...get a good set of pans!  I hesitated to even get an induction because of having to replace my pans, that I really liked, but ohhhhh, I'm so glad I did!  I chose CIA.  Yes, the CIA does make some noises, but even Miele says there may be some noises.  I found the CIA to be much superior to other cookware I had test drove...but, I didn't get to try the Demeyere as they were out of my budget, so I can't talk to their quality or the response.

I chose the 30" because I didn't see the need of a 5th burner and my old cooktop was 36" and I welcomed the 6" extra counter space.

The reason we went with Miele, specifically, is that the one of the sales people told us that Miele is using 4th generation technology...where as, even Wolf is still using 3rd generation.  Which has to do with the configuration of the inner workings of the 'hobs'.  After his explanation, we wouldn't consider anything else.

After only one week, I'm extremely happy with my decision to get an induction and a Miele.  Now, if you'll excuse me I have some cooking to do!
