Halo, Empire 1 and 2 force feeder. So on and so on.
Cool look, fast feed rate, bending 6 prong rotor.
The feedneck at the end makes it slide a bit.
Great hopper. If it is being compared to a Halo, the "best" hopper in the game, than it has to be good. I honestly don't see the point of buying a Halo with an Upped board. If you can pump out 32 bps on semi, more power to you. I've never had a problem with it. No breaks, no body cracks, and the battery life is better than decent.
Buy it. If you are looking for an electric loader, this is the one for you if you don't have 150$ to spend. Find it for 35 on eBay. It wont let you down.
