vlocity-more expensive (even with the 440 installed)
halo- not as good
proto matrix rail (olive)
proto 2 piece
68/45 crossfire tank
Low ball capacity
This loader i got new for 69.99 i was amazed!!! i have a vlocity, halo, magna drive, and the new pinokio but i think this is alot of bang for your buck!!! its light, fast, less expensive than the vlocity, magna drive, and pinokio even with the 440 motor and loudmouth, i love this product and great job hard corps for a first loader!
i HIGHLY reccomend this hopper from a stand point of 10 years of paintball experience
