We’ve had this mailbox for over a year now with no issues. My two year old son likes to check the mail with me. He always wants to lock and unlock it, so I help him insert and turn the key. So it’s not a difficult lock where you really have to jiggle the key to get it in there just right, like some old locks are. The mailbox is big and can hold many of the smaller packages we have delivered. And I like that I don’t have to worry about the mail getting stolen out of our box.
