weight, feedneck, maintinence, and price
Speed- one of the fastest hoppers out there with the exception of the victory board Halo and the Q-loader(who needs em?).
Ripdrive- allows you to preloadballs, clear jams,and keep in the game when batteries die. Extreamly nice for chronying you marker without turning hopper on.
4 and 6 battery holsters- 4 battery is nice because it takes weight down a bit and uses less batteries. 6 battery is nice if you are up for a long day at the field and dont want to replace those batteries for the day. Also it gives the hopper a little more juice. I'm personally just sticking with the four.
Colors- go good with any gun, yellow, blue, black, and clear.
Durability- reinforced feedneck and just a solidly built hopper (you can thank halo for that)
Profile- very small profile, especially from the front, anything that hits near the top is going to bounce.
Weight- The things a whale when it comes to wheight, but no more than an egg when both are filled.
Feedneck- Takes forever to sand down to fit in almost any gun. I had to force it in after sanding it the first couple of times and it cracked the reinforced feedneck.
Maintinence- Takes a day and a half to take apart and put back together (becareful not to break of the button when you do).
Price- A little hard on the wallet but worth every penny.
Empire souped up a halo to make the best hopper on the market. The pros totaly outweigh the cons. Props to both the people and halo and the people at empire.
