This is our second induction cooktop.  Our first lasted just over 3 years.  Wasn't happy.  Our new cooktop model replaced the one we had.  This cooktop has a lot of power unlike our previous stove.  Water boils quickly unlike our previous cooktop.  It was probably a lemon from the get go.  The main problem with our new cooktop is that the controls are hard to read on the black surface.  Grey on black just doesn't work well for people with low vision issues.  Unfortunately we ordered at a showroom that did not have our model in stock.  So we ordered from their catalog.  If we purchased the white cooktop we would have been completely happy.  This is why I could not give this 5 stars.  My mother cannot use this stove at all.
