The Rev 12v will reliably prevent paintballs from
getting "jammed" or "clogged up" in the hopper when you use
higher-end low-vibration guns. The 12v will, for the most
part, keep feeding paintballs fast enough for high-end all-
mechanical guns.
Weaknesses:
Although it's based off the VL200, and the packaging states
that it can hold 200 balls, you shouldn't fill the hopper
to capacity. You need to leave a little bit of room so
that the paddles can move the balls around when they get
clogged up together.
Conclusion:
The 12v isn't cheap, and whether it's really worth the
price is debatable. Unfortunately, there's not much in the
way of alternatives. The eVLution motorized hopper is
supposed to be better (by offering more consistent feed
rates), but it also costs more.
If you need a motorized hopper, the 12v Rev is a good
choice.
would not recamend for an autococker... if u feel like you
need a revolution hopper, get a 9 volt, less expensive, and
the autococker doesnt have a really high bps rate anyways..
so a 12 volt would be a waste. but it is a good product.
