We have built it into a Wandniesche and if the now wants a crack, then even more difficult to crack with brute force alone the limited accessibility.
Is already written shortcoming as well as in other reviews, the Packaging - Packaging non-existent - as well as the original box. (No deposits, etc. placeholders nix) had the vault (thankfully behind) a completely scarred corner - on the surface was apparent that this was already under way, that is not happening at the transport to us.
