I replaced a 27 year old Jenn-Air with this unit and I could not be more pleased. I like how fast the burners light and the simmer burner is perfect for my uses. The only complaint I have is that GE had a fit guarantee program and I found out too late to use it. This unit is slightly smaller than my old cooktop and the GE unit does not use any draw down clamps so I had to have my contractor shim the opening to secure the GE.
