A hit and a regrettable miss, but correctable
"This is the first GPS mag carrier I bought. Great for eight mags, lousy for any more than that. Why? No velcro retainers for each mag. If you fill the case with 16 mags and open it up like you're going to hang it on a hook, 8 of the mags will fall out. So you really have an 8-capacity case. Easy solution is for GPS to add velcro retention straps for each mag, just like they have on the "open air" version that was my second purchase and works great."
