3 of my teenage kids and one 2 yr old nephew crawl all over my house. I have one of these under the bed, screwed to the floor. I programmed it with a code that I can type in without looking. I keep 3 loaded handguns in there along with extra mags. It could hold 4 if I didn't keep the mags in there. I also keep a dessicant pack in there too.
