i have all three hoppers (pulse, velocity and reloader B)
reloader B, switch on, THEN load your paint in, nice on your battery life because its not trying to feed balls all the time. Its REACTIVE, hears gun fire, feeds paint, no noise, stops feeding... once you have set it, what is there to change??
The other two aren't as nice on batteries UNLESS you get upgraded chips for them or the Rf Chip with the pulse because they are PROACTIVE they are trying to feed paint all the time.....
team members use all three, and each prefers a different one.....
(basically they all do the job right, and get paint to you marker faster than you can fire)
i haven't tried a Torque yet.......
