2003 Autococker Vert Feed
I bought this and the gangstar chip at the same time. Never tried it with the stock chip, so I can"t speak for how well that work. But with the new chip I get at least 4 cases out of a set of batteries. I can use them more, but I feel better replacing them. It is very durrable. Has been dropped a couple times but never had a glitch. Feeds fast as hell. What else do you want in a hopper.
Get the gangstar chip, that will bring out the full potential. I'm gonna give it a 10 cause I love it.
