Product review (1 stars): MANY DEFECTS
We've had this cooktop going on 5 years.  For the money it's beyond substandard.  The knobs CONTINUOUSLY break because the base of the knob is cheap, thin plastic.  The interior valves are also substandard.  They use plastic on the interior of the valves so if something is on the stove for an extended period...like soup or applesauce or marinara sauce - the knobs and valves would start to stick.  After several hours on the phone, GE sent replacements for all 5 interior valves as two of them completely locked up at one point and could not be turned on or off.  Really not an ideal situation with a gas appliance.  We also had to pay a local tech for the install.

We love to cook and thought this would be a good investment - but sadly there's zero pride or quality in the "craftsmanship" of this product.  DO NOT BUY IT.
