No brand name, no reviews, no listed internal dimensions and basically no warranty. That's a pretty unwieldy 725 lb. product to return if it sucks. The best info I see is that it is 725 lb.
Costco has a 700 lb. "72" gun 43.8 CuF w/ 60 minutes for $700. Free safe replacement after burglary attempt. (You'll probably need to fill it up w/ new guns or buy yours back from the pawn shop).
