one of these was used to film the first leg of this years pa xball, attached to Chris Edwards gun, the picture quality was remarkably good from what i have seen of the footage, i was expecting blurry crappy images but they were far from that and the sound wasnt too bad eather....very noisy strapped to the gun but you could hear players talking etc....and the added bonus of where it was mounted was that you were getting a guns eye view as Chris blasted people to bits!
