My husband bought this for me a few  months ago and I am loving it. Water boils within minutes. Temperature change is instantaneous. The stove is not dangerously hot when the eye is turned off like conventional stove  tops. Not all materials and pan surfaces will work on it though.
We use thin plastic-like covers on the eyes 
to protect from scratching when cooking
(which are not affected by the heat). I would 
definitely recommend this cook top [This review was collected as part of a promotion.]
