We bought this wok about a year ago and used it extensively (at least once a day) with amazing results. It heats up very quickly, is truly non-stick, and a dream to wash (you basically just have to wipe it down and it's already clean). A couple weeks ago, it stopped heating up and we were gutted. Then we realized there's a 2 year warranty and emailed VonShef about our problem with proof of purchase attached. We had a kind and helpful reply back within NINE minutes on a Saturday saying that they will dispatch a replacement item immediately. It was already delivered on the Monday. We are truly impressed!!
