A friend of mine in the safe business came up with this safe. In brief, it is a tweaked commercial fire & burglary safe that has been converted for use as a gun safe. The conversion is essentially a nicer paint job and a gun interior.
The body is cement filled, and has dual 10 gauge inner and outer walls. This gives you a total of 1/4" worth of steel on the body in addition to the cement.
The door is also cement filled, and has multiple steel plates that have a cumulative thickness of 1/2", with cement fill in between.
The safe has all of the other "normal" safe features such as a UL rated lock, mechanical relocker, and hard plate. It also has the addition of a glass plate relocker with an adjustable remote mount. Essentially the relock on your safe may be in a different location than the relock on the other guy's.
The bad: It's a no frills safe. They are only available in two textured colors. The interiors are chunky and plain. The paint is nice, but I have seen better. It's a great buy for the money, but the focus is on security, not looks.
If you have any other specific questions, I would be happy to answer them.
