Horrible cooktop.  I bought this to replace my Amana glass cooktop I had for 20 years.  This one is so bad I'm going to replace it.

Knobs are not real stainless, but plastic painted to look stainless

Hard to clean, even with abrasive cleanser.  When contacted Bosch rep was told to use a razor blade to remove residue.  If I wanted a hard to clean cooktop, I I would not have selected a glass style cooktop.

Only one burner is large, all the other are too small to be of any value, so I ended up just using one of the 5 burners. I bought it sight, unseen so I didn't realize how small the burners were.  Long story short, waste of $800 dollars, I'm going to get rid of it and buy another one.  Don't waste your time with this one and don't expect Bosch to be of any help.  Stick with Bosch just for dishwashers.
