As I said before spinny thing is at back, and front is angled therefore you dont have to lean youre gun back witch makes for very consistent use.
Same price as pulse but I have tryed both because my buddy has one and it is way better than pulse because faster, more consistent and lighter. Also Egg 3 and halo b are about the same but before i had a halo b and it sucked, and the pulse is just a halo b but more upgraded.
And you see more people with the vlocity than with the pulse.
Overall it is A VERY GOOD BUY. I Highly recommend buying this hopper if your looking for a hopper that is not too expensive but will still give you a consistent bps. If u goto ur local paintball store and are deciding between a pulse or a Vlocity...PICK THE VLOCITY.
