Query: Mine turned into a shrapnel bomb.

My lid arrived with the knob as separate parts. It wouldn't stay tight in use. On my last try tightening it, the glass exploded into safety glass bits, leaving shrapnel wounds on my hand. I called the "secret" Amazon customer service number, and was given a refund without having to return the lid (I offered pictures of my sink and my hand). All in the first half hour since the box arrived. I'm still bleeding, but I have no desire to spend the evening at an emergency room.The pan looks great (I have to clean glass from my kitchen before I can try it), but I don't want a replacement lid; I could have been blinded.(Doesn't the two stars make you wonder what it would take to get a one star rating from me?)
