I think I ordered this to lock my chest in college because I didn’t trust my roommate. Or maybe it was just while I went away during the breaks. Anyways the lock was chunky and durable and did the job.

This Master Lock variation is not quite as sturdy & "well built" as the other DISCUS locks offered by Master, BUT when Value & cost is a very important consideration, this lock is a GREAT choice.
