The GE Cooktop is very nice.  I like the features of the touch on/off controls.  It makes cleanup easy.  This cooktop was a replacement for a 23 year old GE downdraft cooktop.  The installation created some extra work to make the unit fit properly.  I would recommend ordering the trim kit when you order the cooktop unit if you are replacing your cooktop.  I wasn't aware of the trim kit until we were ready to install the cooktop.  We had to halt our installation and order the trim kit and then wait on it to arrive.  This added an extra week to our installation.  Not sure why the trim kit isn't just included with the purchase of the cooktop.
