Product review (2 stars): Very Disappointed
As a disclaimer, I did not buy this item from Amazon or one of their suppliers. But I did buy this from another well known internet vendor.

I love the way it looks.  I love the space on the 36" model.  I love the grates.  What I absolutely HATE is the inability to clean this cook top. I clean it daily and have since I installed it last fall.  It looks like it is 50 years old.  Even the area around the knobs have scratches.  When I called Bosch they acted like I was an idiot for complaining about "ME scratching my cook top".  I did not take a knife to it...it occurred during daily use.  I have a stainless sink that has pots banging into it daily and it is not scratched at all.  I've decided they must use the cheapest grade of stainless they can get away with or this would not be an issue.  Would I buy Bosch again....NEVER.
