There have been a bunch of robberies in my neighborhood lately. One thing I've learned: Stay away from the Liberty/Browning safe with the electronic keypad.
The thiefs found, probably by accident, that if one of these units is tipped over on it's left side, hard, the door will pop open. A friend of mine had a bunch of money stolen this way. Liberty didn't acknowledge the problem (safe says browning on it, but its made by liberty) until someone else with the same safe tried it at their house. It worked.
So, take that as a warning.
