If you're looking for a large, basic safe, this one is great!To start, this is NOT a fireproof, waterproof safe and RPNB doesn't state it is.The safe isn't super heavy (around 20-25lbs). Made of steel alloy, the front of the safe is pretty thick, the rest of the safe is just ok. As a deterrent, it's sufficient, and it has mounting holes. Bolted to a wall or in a corner where it would be hard to get leverage, or remove, the unit would be pretty sturdy.The unit comes with 4 anchors, and has 4 predrilled holes in the back and 4 on the bottom for mounting options. After mounting, I found little to no flex in the walls of the safe, and I could put my entire weight pulling and it doesn't move.The electronic lock works ok, but is quite picky with batteries. Put in decent batteries and it works fine. I tried some cheapo zinc chloride/carbon zinc batteries and the lock refused to work. Put in some alkaline energizer batteries and it works great.The safe comes with backup keys in case you want to bypass the electronic lock, or the lock is out of batteries. Having a back up key makes any possible electronic lock problems a non-issue.Overall a decent buy. Works well. Only thing missing might be a light, but a cheap light puck would solve that.
