I bought this to leave at the end of my driveway to sell firewood. So far it has worked well. Clearly if someone wanted to pry the thing loose from the tree it's mounted on they could. That said, it comes with 4 pre-drilled screw holes in the back of it, so it can be mounted securely. The lid is sloped to shed water and it's relatively weatherproof. The lock mechanism is decent quality and it comes with 2 keys. The one reason for not giving it 5 stars is that one of rivets in the lid hinge was loose and rattling around in the box when it arrived. I was easily able to repair the box using a small sheet metal screw, but not everyone will have one of those handy, let alone a rivet setter. It still would have worked without the repair but the loose fit could have invited someone to tear it all the way off.
