Bought this about 2 weeks ago and used it a couple of times as saute pan without the lid. Its OK not bad. But last night try to use it to make stew and had the lid on for the first time. I was standing right next to it and the heat from the stew must have gotten to it (and its supposed to stand up to 500 degree F in the oven). The glass of the lid exploded. Lucky for me it was probably tempered glass. But the glass cracked into a thousand pieces. Some of the smaller pieces went into the food and all over the stove. I was not injured as I was standing next to it and not over it but it was so dangerous. Contacted Amazon this morning and they offered a replacement but we settled with a full refund because no way I am going to use anything from Circulon again.
