Yeah just got my oldgoat bottom feeder today, been vapin on it for cpl hours now. I had some lr 306 attys layin around, and it works great. I havent tried any cartos yet, but im sure they will work fine also. Its not built like a reo, but its made really nice for what it is, highly recommend it for the money. He pays good attention to details, like a little pearl like ball to cover the stock unused screwhole on the batt box. Its takin' a bit of trial and error to figure out how strong and how many squeezes to juice it right. Hes a nice guy and responds quick and will ship it out super fast.
