The locking mechanism depends on a small, fragile plastic part.  It broke after a few months, and the cabinet could no longer be locked.  The manufacturer does not provide replacements for that part, so the entire cabinet had to be replaced.  The cabinet arrives in one box weighing almost 100 lbs. and left by the shipper on my front porch.  Far too heavy and bulky for me to move.  I wish it had been shipped in two boxes, or there was an option of providing delivery instructions.
