model 98, dye barrel, 3000 psi duck tank, drop forward, Zap's Mach 404 hopper
I have a hand-me-down 12 V Revolution that doesn't work anymore (motor does not turn off). I needed a replacement. The zap hopper is a little cheaper than a revolution. From my experience with the hand-me-down rev., it tends to trap balls between the blades and the case, thus the servo motor is blocked and essentially shorted out. Also the rev. tends to stay on at times during a game. The 2 9V batteries don't last long with the revolution (batteries will last 1 day or 1/2 case). I have yet to replace the 1 battery on this mach 404. It never jams. It feeds at 11 bps, which is the same speed for a stock model 98.
Since the size of the shaker contraption is bigger that rev. blades, you may not get as full a hopper as a rev. Also (like the rev.), you should leave some space for movement (don't fill all the way).
Another important issue: it is only fitted for zap guns. I need to put about 2 layers of electrical tape on the neck in order to fit into my model 98's elbow. This is a pain when putting the gun together, but it stays fine for the rest of the day.
I don't think I will ever have to replace this item. Nor do I think I will get/find unexpected glitches, unlike the revolution that occationally has problems.
HAH a revvy does NOT need a battery change after 1/2 a case. i have had one since christmass, and i go out every week using about 700 balls, today was the first time i had to change them. And the not turning off thing would be either your hopper is empty, or your using very dark paint. and for the previous comment ...? what. REVVY all the way
