Ok took my halo to paintball site and it seemed to be working fine until I put it on my gun and whilst I wasn't shooting it would still try to spin then it would flash green red green red quickly which means low battery so I used brand new duracell batteries and it still didn't work just wondered what to do I think it's the eyes on the hopper as when I try put my thinger up the feed neck it doesn't stop spinning so how can I fix this
