Product review (1 stars): Great stove, poor knobs.
For a 1100 dollar cooktop, the knobs are of poor quality. One of the knob broke off while my burner was on causing the burner to remain stuck in the on position. I thought I could simply put the knob back and turn it off, but the whole dang rod into which the knob was supposed to be inserted also broke off because it, too, is made plastic! Now I either have to cook with the broken burner, which happens to be a simmer burner stuck on one setting, or use the full burner with the simmer one on at the same time. I would not buy again
