Product review (5 stars): love it, especially compared to what it replaced
Have only had it a week, but it is a big improvement over our old cooktop. The burners come on immediately, put out more heat, and the cooktop is much easier to clean, and the edges fit snugly against the surrounding countertop. The old cooktop (came with the house) had a tempered glass top and never fit flush, so spills always ran under it. Also, the burner controls were underneath the glass and spills would pour over the controls when they ran down the holes (which was often), whereas on this new cooktop the controls are sealed and are well above the level of the burners. Finally, the grates are wide and flat and cover most of the top, so no more worrying about pans sliding off.

Installation directions are clear and detailed, comes with LP conversion kit we didn't try out but looks like everything was there (and there were directions for installation of that, too), as well as the usual care and use instructions and warrantee info. My only nit is that the styrofoam packing produced a lot of little white pellets when it broke (and one piece broke off in shipping), which required vacuuming the cooktop about 10 times to get it all off before installation. But everything was well packaged and arrived intact, so it's a pretty trivial complaint.
