I've used the warp feed on a Titan, Spyder, Tippman 98, and now my E-mag (yes! finally!)
It feed balls nicly, and with no breaks too!
Love how compact it is, Its my hopper that gets shot 50%% of the time with out it.
Alot of people complain about the wieght... go work out.
Batteries are expencive :(
Defenatly needs a on/off
The wiring is poor, I'm used to high quality from AGD so i was disapointed
that they cheaped out and didn't go with copper wire. The nickle (I think thats what it is) wire gets twisted and will snap because its so thin. That realy pissed me off. (can i say that?)
If you keep getting shot in the hopper or elbow buy this!
Its worth going through the bad, (which isn't so bad)
