Works like a dream! Really fast and super controllable from rapid boil to gentle simmer. Good selection of ring sizes. The thing that I really like and one of the main reasons I bought the AEG is the fact that every ring has its own control so there's no messing about selecting a ring and then changing the temperature which usually results in burning/boiling over. Very quiet in operation. The only slight criticism, and it is very slight, is that the markings are a little on the feint side being very pale grey on a black surface. They would have been better being white so that they stand out.
