We opted for this hob, because it has a metal edging. For three years we have been cooking with induction and do not want to miss it. However, we previously had a field without borders. Unfortunately, this is very vulnerable and within a short time the glass surface is broken. Now we hope that pays off with the edge of the purchase of a field. Now the cooktop itself: It is very easy to use, you need not be an extra to keep the description to heart. Great thing is that each plate has a power function, so that the pot content reaches every Paltte in the blink for cooking. A timer is attending so that you may save the timer. The sound at the end of time is pleasant and not too intrusive. All functions we have certainly not tried, we use the field for only two days. But it makes a very solid impression.
