Product review (5 stars): Love this cook top!
This cook top replaces my 1985 Kitchenaid cook top so it's a huge step up.  The elements heat up very fast but do take quite some time to cool down (not necessarily a problem, just an observation).  The knobs feel heavy duty; they are definitely not plastic.  It looks great in my kitchen and was easy to install!  I have only been using it for about 2 weeks but it's been great so far!
