We returned a cooktop from a different manufacturer because its electronic overheated, it smelled bad, and the touchpad was annoying and unresponsive.  We got this one instead and we’re happy because it has physical knobs that are easy to use, it has a better variety of element sizes, and it has two fans built into the bottom that keep the internal electronics cool and not smelly.  We are happy with it.  My complaints are that it’s a little smalller, doesn’t have stainless steel around the perimeter, and that the strip of stainless in the front is easily scratched.  So, it doesn’t look as good but it works better!!
