Product review (4 stars): Best cooktop we've had
In various homes, we have had ceramic, gas and ceramic with halogen. For us, this is the best we've ever had. Going back to non-induction will likely never happen.  We've used the Miele for two months now and believe we've seen both the good points and the bad.

Pros:

Excellent burner layout. While this may seem pretty simple for any manufacturer to provide, in our looking at many cooktops, it seems to be the exception rather than the rule. Plenty of room between burners, large pots up front or in the middle where they are simple to handle.

It's not about boiling water quickly, it's about control. Better than gas, much better than ceramic. Low temperature cooking is a breeze.  Very quick response both up and down.  Can switch burners on the fly with virtually no heat up time, like gas.  No waste heat and no smell, unlike gas.

Easy clean up. You can clean as you are cooking.  Or lay a paper towel right against the pans if you'e ladling a risotto.  No risk of burning or even getting warm.

Can handle pots of widely different sizes.

As a note on pots:  Older stainless pots/pans may ring when heating up. Our old Sitrams do, new ones do not. Our cast iron pans are the most induction happy. They make no noise, heat up the fastest, heat all the way up the sides almost simultaneous with the bottom, cool down quickly.  After cast iron, our tri-clad pans and titanium Cybernox are excellent.  Aluminum with a stainless bottom is not great. Notably slower compared than the other materials.  If you need to buy new non-stick pans, go with coated stainless. You will pay more but cooking on them is much better than induction ready aluminum pans. We have both.

Power. We use boost frequently and nothing suffers as a result even if 4 pots are going. What's funny to me is the cooktop is on a 30 amp circuit instead of the 50 amp called for (8 gauge wire, short run) as I forgot to put in a new breaker. One of these days I'll get around to it but it's obvious the Miele has a substantial amount of power we have yet to need.

Cons:

The touch controls.  We have first generation touch controls at another home and I detest them. While the Miele's are better, I view them as senseless.  Why introduce a control set that is more difficult to use, sensitive to; leaning on them, covering them with an old baggy sweatshirt that drapes across them, or the towel over my shoulder that drags over them, or a spoon I lean on a pot and the handle happens to end up on a control, or moving a pot and having a control activate?  All while providing no addtional benefit over a knob???  Senseless, give me a set of knobs any day. The touch controls on Miele's oven are a joy to use. The cooktop's are not. Having said all of this, my wife loves them and never has an issue with them. I will admit they are light-years better than the first generation touch controls but, our other cooktop must be 10 years old so progress appears slow in coming.

It's very shiny.  I'm not talking about good quality absolut granite shiny, or the normal run of the mill black glass cooktop. The Miele's surface is like a mirror. As in even a damp micro-fiber is going to leave streaks. An almost dry, completely clean micro-fiber towel is the only way to wipe it off, once any crud or oils have been totally  removed.

All in all we are extremely pleased with this cooktop. The control set being my rationale for knocking off a star. My wife would give it 5 stars.
