The heating zones work well, including the area sensing feature. Looks good. Unfortunately it gets pretty noise on higher settings - lots of buzzing from the magnetic coils. Worst part is the mechanical details though. There are a set of smal metal 'plates'/supports scattered along the edge on the underside of the glass plate. This results in gaps between the glass and the countertop where liquids will happily find their way to you cabinet below if you spill anything. This has to be the worst design 'feature' I have ever seen for anything like this. If you buy this cooktop, make sure you are handy with some clear silicone and that you can lay down a VERY good looking / discrete caulk line! [This review was collected as part of a promotion.]
