This is quick and easy to learn to use and very functional. I have one pot that is too small to be used on the cooktop surface - which I was a bit annoyed about. But I bought a stainless steel adapter plate and that seems to have solved the issue. Also invested in a silicone mat, which seems to be helping with pots slipping on the glass surface. Overall, I'm pretty happy. Feels very efficient. I guess I'll see when the powerbill comes!
