Well I used this a few times and really tested it on a Spyder and shot it like..... 10 bps. It skipped one shot for some reason. It made the gun top heavy even with the 20oz. on it. And since its sound activated sometimes it skips a turn. But other wise its pretty good for a mech gun. But if you have an elec. and you are a back man this is too slow for you to use.
If the hopper isn't always activating adjust the sensitivity until it registers every single shot - the sensitivity adjustment is one of the desirable features of the LCD model over the standard one.
