We bought the cooktop to replace a 20-year old radiant electric cooktop.  The new cooktop was bought specifically because it knob controls and 18 power levels (plus a power boil).  The ceramic glass cooktop is easy to clean.  Pans heat up quickly and control is great... especially useful when using a pressure cooker.  The stainless steel trim across the front gives a smart look to the kitchen.  The cooling fans for the induction power units are not loud enough to be distracting.  As of this writing, the cooktop has been in use just over 2 weeks
