I have only used the cookctop so far but so far so good.  I love the cool cooktop when there is no pan on the burner.  I have not connected it up to wifi yet so excited to see what I can do with that.  The sllek look and knobs on the front and that is what I was going for and this appliance totally delivered.  It was a little on the pricy side but I knew that going in since it is induction which is newer technology.
