i jus got a new halo and the first time i played with it i put brand new batteries in the night before and wen i used it it sed low battery and i didn't play with it like turning it on and off wen i was jus sitting at home doin nothing. then it choped a ball between the feed hole, and the propeller thing and snaped the little beeds off then i bought new ones, put them in, then went out to play and they snaped off the first few shots i take......and it isn't to slow cuz my gun is a GEN x 3
