Better quality than the ones that you get at Home Depot or Lowes. Comes in a little plastic bag with a bunch of adapters. One of the adapters should fit your mailbox style. I keep a couple handy because people keep losing keys, people move out, or people quit from tenant businesses. Five stars not because it is some super duper product but just being mediocre would make it better than the big box store mailbox locks.

The locks are the perfect fit for many different makes of mail boxes. Ordered 2 and they came quickly and were keyed differently which is important for units with multiple mail boxes.
