We bought this a month ago to replace an existing electric cooktop. It was relatively easy to install and very easy to learn to operate. We did a test for fun to see how long it would take to boil a cup of water in a stainless steel sauce pan - it took a minute and a half to achieve a full, rolling boil. I can cook at high heat with very little heat going into the kitchen. Very nice in a warmer climate where we live. The cooktop also cleans up extremely well.
