Awesome first ImpressionSo far, I have very little bad to say about this cooktop. The pro’s:1) Self-contained unit; may sit on the counter or be flush mounted.2) Elegant design, easy clean surface3) Heats up super-fast. I have never had a cook top that heats up almost instantly.4) Easy installation, just 3 wires. Since I was replacing a cook top, I just removed the old and put in the new. (Probably someone with more electrical experience than me will have something to say about my wiring)5) The user’s manual is actually helpful, easy to read and concise.I was frustrated when I first turned it on because I kept getting an “E” on the displays. The cooktop senses if you have a pan on the burner and if you don’t, then you get an “E”. Learned that from the user’s manual.I made the mistake of assuming that it would fit perfectly were my old one was. That was a bad decision. This unit was slightly shorter and fatter than my old one, so I had to cut the counter on the top and bottom and now I have holes on the side, but I can figure out a way to remedy that.To flush mount, the actual dimensions are 29.5” wide, 19.5” high and 3.25” deep.(The last photo is of the old 1960s cooktop I replaced)
