Query: Yup, cracked after 4 weeks of use

Hate to admit it but I am also one to have a cracked 2 quart canister. Two 3 inch cracks appeared at two vertical corners. Looks like the plastic is too brittle and the sidewalls flexing under the vacuum load create stress points that the plastic can't handle. Major bummer since it a great idea and when it works, works very well!Update: DO NOT BUY THIS!!! Two replacments from Tilia cracked and the one I gave as a gift to my dad cracked as well. The smaller versions are holding up ok but the 2 quart is a no go.
