Before purchase, I did a lot of background research on different manufacturers.  This GE Cooktop had the best ratings and features.  I am very pleased with the streamlined look, the absence of knobs - yea! - and the ease of use.  The Lock feature answers the issues that some Reviews noted, so the cooktop will not go on randomly with slight touch, so it is very safe.  I love the two burners that can sync to create a large cooking surface.  I have only used it for a few weeks now, but so far it is very awesome!
