I am just so disappointed with this hob. Always loved Zanussi products, but this hob does not come up to expected standard. I have cooked stir fries (on hottest ring P setting) Ultimately it's fine for a couple of minutes then appears to turn itself to a lower setting ending with 'stewed' stir fries!!! If I use more than two areas at once, the power drops. Tried to phone Zanussi, but was left on the phone for 25 minutes. This is my 3rd induction hob over the years, (various manufacturers) and I am sad to say the worst one.
