Product review (5 stars): happy camper, performs fine
I'm happy to say that my cooktop has performed with no issues and continues to do so after four years - knock on wood.  Sure, the touch control can be a bit sensitive, but nothing that you can't get use to.  I use Scanpans (CTX) and old Amway and cast iron cookware on it, and really enjoy its heating efficiency and not having wasted flame and associated heat.  Cleanup is a breeze and I occasionally use a glasstop cleaner to keep it looking brand new.  Very satisfied!
