Its an OK hopper for just messing around in your backyard or at a crappy little homemade feild. I bought this hopper just so I would get better at making my shots more effect because I will carry only 50 paintballs. The feedneck jamming problem was easily fixed by filing down the edges around the opening of the feedneck. I'll keep it just as a backup hopper for messing around but I wouldnt suggest buying it for anything more than that.
Buy it just for practicing but dont expect too much out of the product. (It is Brass Eagle:P)
