anyone have experience with them? Tried checking on google and there wasnt much and most of the threads on ar15 are pretty old and only have a few responses.

what im looking at.

Had nothing but good experiences with them.  Electronic lock died, they sent me a dial.  I have moved this safe twice by myself by disassembling it and even got the door back in place with a hand truck.  Highly recommended.

Seem sturdy?

I need to get it in a 120 yo basement. Seems like the best option.

Love mine. It’s been in my basement ten plus years. Moved once but not disassembled- I just removed the door and slid it over the carpet. ETA: the box was tight even with me pushing it around. No wobble.

I added a Rack-Em pistol rack mounted to the door and a drawer that hangs under the shelf. Add some Akro bins for mags, choke tubes, etc and it holds a lot.

Oh, and a 4 bar LED light kit off amazon and goldenrod.

I have the ZA-II 5’ and had to wait six months to get it back when.

I don't have one as I don't have the space, but I did see a used one in person and examined the bolt works.  The box is incredibly strong and the top is like the top of a shoe box, with overhanging edges and creating an additional obstacle to prying apart the sides.  The bolt works are fantastic, with the solid steel bolts spanning the entire door -- no hidden chinsy mounting hardware here.  Top quality with everything.  The only downside is no added fire protection, which is dubious in the first place with most safes.  You could always buy the version without an interior and build your own, with fire retardant sheets installed, build a fire-safe box or closet around it.
