Product review (2 stars): Bosch Not The Quality You Would Think.
I purchased this cooktop 1 year ago and wish I had just returned it.  You can tell right away that the unit is not as quality of a product as what you would have thought with the Bosch name.  We are a two person household and the unit receives light use.  Quite often with a burner lit, the igniter will continue to fire even though you have a good flame.  Also the black labels for the control knobs are wearing away so within the next year we won't be able to tell which knob controls which burner.

I should have saved the money and purchased another brand!
