Product review (2 stars): Won't meet expectations...If you do a lot of cooking!
THE GOOD - Installed this Feb 2015 and was very happy with the way it looked on our island.  Nearly 2-years later, we haven't had any performance issues. Only option was electric and this product seemed to be the best price/performance mix at the time of purchase.

THE JUST OK - While the cooktop has not stopped working and we haven't issues with operation, it does take a very long time to heat up your foods and brutally long to boil water.  If you are used to cooking with gas, you will not be super happy with this type of cooktop.  If you cook often with a lot of pans, the small front burners could be better placed as sometime pans to fit as you want.  ALSO - as other reviewers have stated, you have to be very committed in order to keep this thing clean.  I'm sure this is the nature of this type of product, but if you cook a lot, know you will be cleaning a lot.

THE BAD - Glass cooktop chipped and a large crack has occurred near the knob location.  Sure, we must of caused it, but neither cook in the house can remember when the chip/crack happened.  Note - the warranty won't cover this type of accidental coverage and there is NO fix for this type of issue.  My reasoning for a 2-star review is simply the lack of either a better design (full frame) or warranty coverage makes purchasing this cooktop a high-risk proposition.
