Bests & Worsts Reviews from Amazon

I am aware that there is another review saying the same thing has happened,dated 2009. We bought this pan and really love it, and use it nearly daily for soups and curries, etc. We've had it for some months and have used it with the lid on, quite often. The other day, we had a chana masala dish simmering (medium-low) with the lid on, and the whole lid shattered. It sounded like a shotgun going off, or like a small transformer blowing. There was no glass in the food - in fact, it may be a corning-type glass designed to take heat and to break with rounded edges, like windshields. I have contacted Cuisinart and was told that we would have to pay shipping and handling. I find this outrageous and unnacceptable, and am pursuing the issue further. What I want to hear is that Cuisinart is aware of the situation and concerned about possible user endangerment. Perhaps this is a rare event; perhaps the fact that there's no vent led to this situation. Maybe there's a flaw in the glass. Whatever the reason, it's been reported twice on Amazon, so leads me to believe that not only could it happen to others, it probably has done so. I do not know whether the previous reviewer told the company, but I would hate to think that two years (at least) have passed with no change to the design of this pot, if Cuisinart did know of the problem. Cuisinart customer service was prompt and polite, so I have no complaints about that.
