It took me forever to replace my cooktop, but I'm so glad I finally did and that I chose the GE Profile!  My old one was shiny glass on top, and it always ended up with streaks that were so hard to remove because of grease and oil splatters.  I was concerned about having to constantly clean under the heavy grates, but the beautiful stainless steel of this product wipes right up and doesn't smear!  The grates lift easily... I should have done this a long time ago!  I love the lights on the knobs.  The ONLY thing I noticed on mine is all of the burners except the smallest one have a pretty high temp for "LOW"... LOW is always a simmer with small bubbles... if I just want "warm", I have to move the pan to the smallest burner, which isn't my preferred burner to cook on.  That could be a setting or due to the fact that I have an LP conversion... but it doesn't really impact me in a negative way so it's pretty insignificant.
