The company shows the small, pistol sized units covered with framed art, and the larger, rifle length units covered by a large mirror. They also suggest placing one in the back of a closest.
The idea is sound, so long as you accept the fact your guns are not secure, only stored discreetly. I'd like to see one of these with an electrical panel cover. Placed in a closet, this would make an easily accessible, but well-hidden storage site.
