A guy that use to run a field/store, gave me this when he went out of business. ALthough some of the other reviews make the mask seem like it sucks, it really isn't that bad. I have never once had my mask fog up on me. I have played in a tournament, and twice a week since the day I got it, and still no trouble with it. I haven't changed the batteries yet either. It is a little loud, but nothing that affects the game. Get this fan if you have a JT mask
