Not bad for the money. Around 70 bucks. Designed to be placed inside your sheetrock and the "dead space" of your outside wall. Not rated for fireproof though, and someone can tear it open if they tried long enough, but good to keep kids out, keeping things concealed (place inside your closet as shown in the photos). Could put other preps in there as well and not just guns.
