Product review (5 stars): Love it!
As with another reviewer, I upgraded to this model from a contractor's special cooktop after a burst pipe in our kitchen forced a major remodel.  Hell, insurance was paying for it, so I was going to get what I wanted!

Yeah, if I could've gotten the 36" version into our space, I would've.  But we are limited on space, and I needed the 30" microwave vent fan to handle dispersing the heat from the cooktop.  I cook and bake a lot, so I generally know what I'm talking about.

The likes:  center burner handles stock pots well and boils huge pots of water for pasta, soup, etc very quickly.  Our old cooktop took upwards of 20 minutes, while it takes less than 10 minutes on this one.  HUGE like!!!

Very easy to clean.  Grates are heavy duty cast iron.  Burners light quickly and temp is consistent - another reason I love cooking with gas.

Perhaps the only thing I don't like after putting this through its paces is that if you use a double burner pan, one burner on each side (back on the left & front on the right) are geared for simmer.  To get consistent heat for front/back burners, you need to drop the full power burner on each side to half to compensate, while the simmer burner is on high.  Not a huge deal, but I'd like if there were only one burner for simmer.  Or none.  A good cook doesn't need limitations like that.  There, I said it!

Overall, I'm impressed with the feel of this cooktop.  It was definitely worth the money I paid for it.
