We've had this cooktop for a few weeks and I have nothing bad to say about it. Boils water really fast, temp control is more precise than radiant electric, and the burners definitely cool off quickly once the pan is removed. I read a couple reviews prior to purchasing that said it is noisy. There is a slight hum when it's on higher power, but nothing I would quantify as noisy. Overall I am extremely pleased, even though I had to ditch my old aluminum cookware. [This review was collected as part of a promotion.]
