Overall a good hopper. Good for anyone who isn't going to play a stealth position. Bad for sniping in wood ball, but efficient for speed ball. It is worth the buy at $30. Can feed more rounds than a gravity hopper. Think about using rechargeable batteries, or it will waste more money than it is worth. I played an entire day without a single double feed or any chopped balls. I would recommend this hopper for cheap people like me who don't feel like spending $100 on a hopper. I'd rather buy a new barrel with that money. This hopper is good for someone who doesn't have a super fast gun like an angel or an autococker. If you have a fast gun it would be better to buy the more expensive one, like a Halo B.
There are better hoppers, but most are too pricey. This hopper is efficient in speed ball, but I would think twice before playing wood ball with it. It is definitely worth the buy at $30.
