Cheap.
Holds a little more than most gravity hoppers.
Weaknesses:
Jams easy.
Needs a lot of shaking
Review:
This is by far the worst gravity hopper I have used. It jams easily, and the extra ball carrying capacity isn't noticed because your gun wont shoot. The extra size isn't worth it and is the only thing going for this. It adds to your profile. It has a trench in the bottom that is supposed to help load a few balls in a string, but it really works the other way and hinders loading. This hopper requires too much shaking and is not worth it.
Conclusion:
Just get a regular VL2000. They feed much more reliably, and you wont waste your money.
