Product review (1 stars): Junk, Junk, Junk!
Junk!
Sparking incessantly, knobs break if removed, scratches easily and, worst of all, Miele customer service assumes no responsibility whatsoever. We've had the darn thing for over 10 years and never has it worked properly. We no longer use the larger burners because of the spark annoyance  and only use the smaller rear three which seem to be spared the problems. Their customer service folks deny there's a sparking problem, even when I sent videos via email and referred them to the numerous complaints found all over the internet.
Won't ever look at Miele products again.
