Product review (5 stars): They all work well (heat quickly and glow to show they are hot) and look great. I've read a couple of the negative reviews ...
I have bought 6 of these. 2 were bought many years ago for a stove in our old home where they were used for years before we moved and left them behind. 2 were bought well over a year ago and have been in constant use in our new home since a kitchen remodel. I bought 2 more for my mother in law about 2 months ago. These have also been in constant use. They all work well (heat quickly and glow to show they are hot) and look great. I've read a couple of the negative reviews below and completely disagree with them. They are glass tops, so they should be kept clean. Yes, if you drop things on them, they will chip and break - duh. Yes, if you don't pay attention and think you are ordering white tops instead of black ones and you then get the black ones you will be unhappy. Yes, if you just slide heavy pots around on them and the pots have a rough bottom or slide over grit, over time, the glass will get marked up. My wife does not particularly take any great care during her cooking on the stove tops and cooks every day and then some. Our tops still look like new. We also swap them out for the grill and other accessories like deep fat fryers so the cook tops get jostled about some. But 95% of the time the cooktops are in place and being used. If you treat these as the (retail price) $300 plus items they are instead of a $15 coil on an older stove, they will last a very long time.
