I have an older 72" box made by the same OEM. it's pretty solid, better than anything you're going to find in a store but not quite on par with, say, a KRL.
read the description carefully, they offer two versions of that box, one with friction detents and the other with raise and release latches similar to Craftsman Griplatch. I don't think you'll like the detents. some of the drawers take 40lbs of force to open and the tools in the drawer go everywhere. they are impossible to open smoothly. my only other complaint is after 7 years the widest drawer is sagging enough to hit the drawer below it with 100+ pounds of sockets in it. in the end I'd say they are a decent technician quality box for the price.
