I picked one up a couple of years ago. It sees a fair amount of use and seems to be holding up well. My zippers are fine, thank you.

I keep it "loaded" will all my range gear so all I have to do is drop in a gun, grab an ammo can and go.

I use the internal bag during matches to carry my stuff around (ammo, keys, phone, snuff, etc.) because the bag is pretty large to lug around all day.

AND, I like the brass bag too!

AND, it makes a pretty good rest when shooting a rifle from the bench. Not great, but good.
