This safe is so much more sufficient to my needs than I thought! I fit all my jewelry inside! Plus it fits whole notebooks I was able to stash about 8 of my collectible edition Rolling Stone magazines in there, too. I love the shelf they provide, you don’t have to use it if you just want a wide open safe. But I like it. The safe shipped fast and arrived 10 days sooner than expected. It requires 4 AA batteries.  Very easy to program your code.  Hardware is provided for installation into cement (1 anchor and bolt) also 2 master keys you will store away from the safe hidden. I’m very satisfied with my purchase and think you would be too.
