when you turn your hopper on make sure you are in a quiet place untill it completely cycles up (the rip drive gives a lil spin) then your hopper is set for it to go when your marker is fired. Like the guys said this is sound activated and rely's on a sound level it gagues when it is starting up. If you are around firing it will set itself so high that the sound of your marker firing is only occasionally being picked up. There is no way i know to make a reloader b go constant. Hope we all helped and Keep it up and firen man!
