I put a head on it that my son does not use anymore (he is 13). I think this product is excellent, it has improved his shot speed and quickness of his delivery on feeds.
Ok thanks for the feedback. I try to keep him practicing with the same head that he uses in games, to avoid any issues with switching from one to the other (sometimes one throws lower, or has different pocket, etc.). Not a big deal though, and he has a few that are very similar anyway. Thanks again.
