I wonder why they DIDN'T make it out of steel ( except cost, of course ), and secure it better? Masonite? Ouch!
Now that's better. In fact if you notice the last picture shows it hidden behind a swing-out mirror!There's always the Stack-On "In Wall":
Stack-On IWC-55 Full-Length In-Wall Cabinet - Amazon.com
It's no heavy duty safe, but with a little creativity, it could be hidden similar to the TacticalWalls.
