I know the thread is a little old, but I have a StackOn that is very similar to the one you’re considering on Amazon. Close enough that other than the design of the keypad plate, it might be the same manufacturer. I like it for what it is, and it’ll keep honest people honest. So it should keep your roommates from fidgeting with your toys just fine - or even the handgun that’s in your future. If you’re worried about your housemates, or their friends, trying to break into it, I might consider finding new people to share space with.
I’m in my own house, so mine is primarily used for important documents (birth certificates, passports, etc), emergency cash, some coins, and my two primary EDC pistols. Keeps the kid’s hands off of things (though at 15, he knows safe handling and shoots competitively) and is a deterrent for any other visitors in the house, invited or otherwise.
But the real reason I’m posting is just a reminder that ‘out of site is out of mind’. Someone really determined will get into almost any small safe eventually, and if it’s got a key (like that one does) it can be picked. Bolting it to the wall is mandatory, and bolting it to two surfaces is even better. Mine is on a shelf, bolted both to the back wall, and to the shelf from beneath. But more importantly, unless you have reason to, very few people are even aware of its existence, let alone its location. You can’t attempt to access something that you are unaware of. So don’t even tell your housemates you have it, let alone where it’s at or what might be in it. And then, if convenient, stack a folded blanket on it, and let it drape over the face, or hang shirts and jackets in front of it, or whatever camouflage technique might be applicable in your situation. Even my larger cabinets are hidden in plain sight, so a casual observer, or even a would be thief in a hurry, might just pass right on by.
Out of sight, out of mind.
