Product review (5 stars): So good, I got a new one!
Just installed this new model 36 inch GE induction cooktop three days ago. The installation only took about an hour including electrical connection. This cooktop is replacing the exact same model we had installed in our old kitchen from about 6-7 years ago. I have always raved about this induction cooktop and I would not replace it with any other brand or type. The price was right, it heats up in a hurry, and it is very easy to clean. I believe induction, with the right pots and pans, to be better than any other type of cooktop heat source. And because we've had no problems with the old one, when we decided to remodel our kitchen we kept it, it was that good and held up great.  Since the beginning I have been using cast iron pans -large and small- and other heavy gauge pots and pans. It held up great with no scratches or cracks whatsoever.
However, after re-installing the original in the new granite top without any problems, a drill fell on it while tightening up the vent hood above. This caused a crack about three inches from the corner. As I said I would not replace our favorite appliance with anything else, so we ordered from Amazon this same GE model and got it within four days.
There are some differences between the older and the newer model however.
* The newer model has a front and back stainless steel edge covering the glass, where the older model had a handsome curved glass front.
* The newer model has a smaller diameter cable going to the junction box, but the wiring is still the same gauge within it.
* The original baffle plate that screws underneath had a 1 inch rubber extension flap on each side, whereas the new one although it is the same  length with the old one has no rubber flaps. The two new small baffle screws were course-threaded (nit picking) where the old type were galvanized machine screws that would not easily strip the holes in the housing. I kept the older baffle plate because the new one was bent inside the box when it was delivered by UPS. There was not much protection for the baffle as it had no styrofoam around it and it was right up against the cardboard side. Amazon has to communicate with the shipping companies to be more cautious with some of these delicate electronic appliances.
* One important difference was that the new model had the improvement I always was hoping for in my old cooktop and that was that the burner glass top areas are now more defined. In the past I had a little difficulty sometimes in keeping the pots/pans on center.
*There was one disappointing difference with the new model and that is the increments on the controls no longer have the .5 (half) increment.
The older model would go from L- 1 - 1.5- 2- 2.5- 3- 3.5 etc, the new one goes from  L-1-2-3-4..... .
We did find the half increments useful in the past.
* Finally, the new model has an ethernet port (RJ45) underneath. I am not sure what purpose is serves, but I sure wish that it could be used to re-program the computer to re-introduce the half increments.
Overall We are looking forward to enjoy this GE Profile model for years to come as we did the old one.
