Good size for storing valuables you wish to protect from casual observers and fire/water damage.  This will not prevent theft as two people can lift it out of your house and the hinges are exposed.  But I figure if you want it that bad, most safes won't stop you.  But I'm more worried about the danger posed by fire and flood, so this one works.  The interior lockbox is a nice add as well and the pockets in the door are great for paperwork.  The only drawback is if you want to mount it into the floor, it is no longer water proof.
