Query: Older canisters good, new ones bad

I have used the Foodsaver line of products for years. I have many round and square canisters. The only ones that last more than a couple of months are the older ones. I have had new ones crack immediately. You can send them back over and over again, but eventually you give up. Unfortunately you can't buy the old canisters...funny thing. Other than the canisters, the rest of the products work well. I agree with others in this forum: I would give zero stars for this product if I could.
