also because it "forces the paint into the breach" it allows the marker to be fired upside-down, and sideways, because it will continue to feed the balls regarless of gravity.
It also has one of the highest feed rates on the market. making it almost impossible to outrun with most markers.
biggest drawbacks?
Weight - it makes the marker side heavy
Cost - its expensive, and you still have to buy a revvy or similar to go ontop of "the box"
Breaks - if a ball breaks in the mechanism, then its an absolute nightmare to clean.
Power - Yet another set of batteries to worry about.
