Product review (5 stars): So far, so great
I haven't had this long enough to judge reliability, but out of the box, this thing is as good as I had hoped. Installation was a breeze, given it's a cooktop - put some included foam bordering around the underside glass, screw in a baffle and some anchors, connect to power, and drop in. Thumb screws lock in some anchors, and it's done.
Heat is nearly instant (water comes to a boil in 1-2 minutes for me), and the controls are about as simple as they can be. Very easy to clean, and just looks sleek once it's in. Highly recommended.
