Product review (3 stars): Some things are very good, others are not
We bought this cooktop to replace one with no simmering ability and open burners.  My husband also wanted the fifth burner.  The reviews were excellent and I had read a number of reviews regarding other cooktops that dissuaded me from purchasing them.  We have had this about two months.  The control of the cooking is great.  I could not ask for more, actually, my husband could not ask for more.  However, I wanted to clean up the mess after he had been cooking.  I took everything off to clean it.  You must be very, very careful not to use anything but a soft cloth on this stainless steel or it will need to be buffed out (assuming that is going to work).  That was the first major irritation.  However, the most disturbing fact is that I wanted to clean around and under the knobs.  I made sure they were in the off position and pulled straight up as the directions indicate in the manual.  I put them in some soapy water, also okayed by the manual instructions.  When I went to put them back two of the knobs were broken.  The shaft that connects them to the cooktop are plastic.  They were broken.  I want to assure you that I am very careful with my things because I want to keep them nice for as long as possible.

I am now hoping GE will cover the knobs because clearly within two months it is still under warranty; however, we will see if knobs are included in that guarantee.  GE wants $41 a piece on their website and I have found those knobs online for just under $21, I don't know about shipping.  Wow, who knew to ask that kind of question.  Oh, by the way, if I try to clean your cooktop and remove the knobs like I have every oven and cooktop I have ever encountered for over 50 years, renting or owning, do I need to worry about it costing an amazing amount of money to replace them (or hope they are covered under the warranty - though clearly at some point, unless I never take the knobs off and deal with the built up dirt I will risk the same thing happening).

I would not buy this cooktop again.  I bought it for the closed burner system because my husband is not the cleanest cook in town; however, I did not realize I needed to ask if GE's cooktops were divas?  If I break all five knobs at GE's price it would be a little less than 25% of the total cost of the cooktop.  Really?  For the knobs?  Oh my goodness.
