"the speed loared is great, i dont see anything wrong with it. great for if you have multiple mid/low cap mags. otherwise, i dont recomend it. if you have high caps, just use a small bb bottle that small amounts of bbs come in, trust me , it is much easier. aslo if you have pistol mags, this thing is too big, there is no way that you would need to shoot 470 rounds from a pistol, i barely go through a 90 round speed loader, considering most pistol mags strech anywhere from about 12-25 bbs. only get this if you have multiple mid/low cap mags"
