It's a pretty standard dump pouch and I didn't expect much for the price. It works, holds a few mags and the drawstring works fine. I didn't have any problems with mags falling out, I am however switching to a drop leg dump pouch.
Fits a few mags
Molle works great
Cheap and does the job
The NC star dump pouch is my favorite dump pouch that I've came across. Has fully adjustable straps. It stays in a spherical / boxish shape which I like. It's not stupidly big like most and yet not to small. I utilize this dump pouch for anything that comes across and I find it very useful to carry my propane tank and adapter when I use my mp9.
Holds quite a few magazines
Great for storing magazines and various items
Keeps it's shape
Isn't the biggest if you burn through a lot of mid capacity magazines.
