Wow, after using exclusively an old fashioned electric coil cooktop for 30 years the switch to this smooth 4 burner cooktop was awesome. Temperature Control Of course, for me there was a learning curve to getting the temperature right for different cooking situations, but it did not take long to figure out how quickly and hot each burner was. The unit has one medium size burner in the back designated as the "rapid boil" burner, which as the description implies heats up faster than the others, and I like this because you can bring water to a boil in a matter of minutes, depending on the size of your pot. Heat Distribution Each burner heats evenly, and I do not notice any hot spots. Durability It does what it is designed to do, and has not caused me any issues at this point, which is 3 years now. Ease of Cleaning This is the only area where it can take a little bit of doing to remove baked on grease. You certainly do not want to scratch the glass, so using non scratch scrubbers is essential. I have been known to carefully use a single edge razor blade to remove grease.
