Product review (1 stars): would not purchase again
My husband purchased this cooktop for our recent kitchen remodel, and while we love our other miele products (vacuum cleaner), this product has been a very poor performer.  We've used induction cooktops before (Wolf brand) with no trouble.  However, the miele cooktop is often times unresponsive - for some unknown reason, the buttons often times won't work when pressed.  A service person evaluated the problem, and said that we need to use our thumbs instead of our fingers to use the buttons (??!!).  The cooktop also has the very annoying habit of turning off completely if something other than an induction-suitable item is placed on the surface (other induction cooktops might have the same function, I'm not sure).  So, for example, if a lid or spoon is on the surface, it will turn off.  Then, it's a coin flip as to whether the buttons will work well enough to turn it back on in time, which leads to a somewhat stressful cooking experience.  We use the stovetop daily - probably 3-4 times a day, and I would not recommend this product to anyone.  Sorry miele!  I do love your vacuum cleaners.
