Pros- Fast- It is fast after you upgrade it, i would recomend the virtue or gangsta chip.
Light- This hopper believe it or not is actually about an ounce lighter then the vlocity select force.
Tight- This is no bs whether you play front back or mid, this is so tight that you rarely get hopper shots (at least to the front)
Cons- It is just a little high, but no big deal.
Honestly this hopper is the way to go, Halos and Empires are so bad, there heavy as all hell, and are huge, with those its like carrying a damn brick ontop of your gun. Also alot of people dont know this bu a halo ways about 2.5 pounds WITH paint, the vlocity ways just under 2 pounds. Go with the brand the made one of the first electronic hoppers.
