We got it about a month ago. Love the auto pan size sensing, the power boil feature - on every burner - is really great, the control is really easy to use.  And it is really easy to clean!

There are only two things that surprised or bothered us.
1) the fan can be very loud when the unit first turn on. Maybe the noise of cooking eventually drowns it out do that it is not as obvious later. 
2) the surface of the cook top gets fingerprint smudges really easily. [This review was collected as part of a promotion.]
