Query: BEWARE! BEWARE! BEWARE!

Don't say you haven't been warned. I have had 2 of these products crack after first use. I bought 3 and Amazon already replaced one. I'm trying to return ALL of them. There is some sort of design or manufacturing flaw in this product.Don't get me wrong, I love all my other Foodsaver containers, but NONE of them have cracked on me like this one.UPDATE 10-26-2005: The 3rd one developed a crack just like the previous....go figure.
