Title: Cannisters are useless and expensive
Review: FoodSaver 3-Piece Canister SetAll my Food Saver Cannisters cracked within one year. They were carefully handled by one adult, following all instructions of no dishwasher, freezer nor hot foods. I have all the clear and black models. Their center bottom seam gets hairline cracks, then fails to vacumn. They are expensive and useless. The unit works well with mylar bags or mason jars.
