I Have a westinghouse model: WHI644BA. We Have been Using it for 4 months. I noticed a number of cracks in the middle of glass. None which start from the outside edges. Nothings been dropped on it. Checked the middle of glass by pressing down with my thumb and it flexed. It has no support. I have been happy the way this cooktop works but I am very disappointed with these cracks.

Had this cooktop for two years now and still very happy with it. Our first induction cooktop, and having eliminated the unsuitable cookware we had, wouldn't have anything else now. Fast to heat, ultrafast on boost. Precise, with very fine control on the lower settings. If the phone rings or whatever, just hit pause and it does just that so you don't burn things while distracted. The only downside is the slick glass allows pans to slide if you stir vigorously, and that means you need a hand to hold on to the pan, but that applies to all glass cooktops. Super easy to clean.

We were talked into this by Good guys, better for you at your age!!! installed yesterday, first off tried 2 pans of water, after 1 hr only warm!!! Then boiled water in a jug poured into a pan with carrots, ( bear in mind when you normally do this water boils instantly!!) NO, 25 mins on power boost, then guess what!!! power boost shuts down, 45 mins of electric to cook carrots, we are aged pensioners, so power is far too expensive for us to be doing this!!!!
