So far so good! I added extended warranty because you pretty much have to these days (needed repair to my first, another brand).  The Power Boil is a great feature. I agree that the warmer burner wasn't necessary~ would have preferred another 8 inch burner instead of that and the huge "Large Burner"  (for canning, etc.) I'll never need. As for its messiness ~ it is. Spatters are everywhere after cooking. The 3-part cleaning kit provided works amazingly well ~ but you must spend 10 minutes after each stove use, and after cooling. I've removed the plastic knobs since they get dirty, as well as under them. This was the same with another brand ~ it's the nature of the glass. Had I known, I likely would not have gone with a cooktop when I built the kitchen (not to mention the difficulty in replacing it). Was aiming for kitchen cleanliness, but must also watch out for crumbs and drips that lodge in small space between glass and counter ~ a design flaw on all cooktops.
