Flimsy Construction on both the plastic container itself, as well as the airtight seal located in the rim of the top. I ordered 2: The first, had a useless stretched out rubber seal within the top and the top does not stay closed securely - with any vibration it would pop open. The second was taped closed with packaging tape - I assume for safer transport - however, the broken off lock-latch was deliberately placed inside the bin before taping it closed. I returned for reimbursement and am now looking at the IRIS products. I suggest moving on.
