First induction cooktop we have purchased and I am unimpressed. We have tried several high end pots and pans and not of them preform to the level as our previous electric cooktop. It take more than 30 minutes to bring four quarts of water to a low boil. Not enough for cooking pasta. Once the water reaches a low boil and you put the pasta in the water it takes another 15 or so minutes to bring the water back up to a low boil. sometimes a pot will work on the smaller heating elements and sometimes not. Sometimes when you are cooking the element will just shut off. after it has been on for several minutes. I find it difficult to cook meal on this cooktop. difficult to judge how long items are going to take cook if they cook at all. Would not buy this product again.
