I'm still shaken by the cover of my Ultrex pan exploding. I took the cover off the pan to add other ingredients. I set it down on the counter, which was room temperature obviously, as I had done many times before, wham! There was glass everywhere, even in my boots. This is the replacement set I recieved from HSN, the other set was recalled because of its explosive nature, and potential for severe damage.....Its all going in the garbage, I'm afraid to use it....Beware!
