The safe is heavy and stable and could be installed as a whole, well, The manual is easy to understand. During installation, however, went out the door Unhingeable a few times and was incredibly tedious hineinzufummeln again. And what is already another reviewer remarked before me, the packaging is very bad because the vault will be sent in the original box and then you can listen to the same a stupid remark by the postman: "Aha .... A safe, ..." and so on, so yes everyone sees that you purchased as a part because you have obviously to keep something. That would have to be changed urgently. But the product I am very satisfied.
