Bests & Worsts Reviews from Amazon

We bought one for Christmas and love the food sealer. However, all the canisters have cracked. So far, still holding the seal, but they are getting progressively worse, so it's just a matter of time. These aren't exactly cheap, so I think it's safe to say that we should expect bettter. UPDATE: These reviews go back to March 2005 and I see other reviews as recent as August 2007...so why hasn't this problem been fixed yet? The sealer is an excellent product, but these cannisters are useless. None of my original canisters hold their seal.
