for $40 bucks.. it aint a bad price.. also... it really shoots paintball on top of paintball from about 50 yards which i think aint bad.. i use mine with co2 and it really helps out out
Weaknesses:
you have to keep adjusting the psi depending upon on hot or cold it is and that pisses me off
Conclusion:
IT really keeps the balls going alot straighter which i guess is what we all really want and they all go very close to the same distance.. not one goin real far and the other comin up real poody (close) I recommend this.. for $40 it can't be beat
