As I assume some of you also received the ad from Dick's Sporting Goods on the Impact Trainer. Basically consisting of a clip on face insert that is used to strike "nerf" golf balls that will stick to the face to allow one to readily see exactly where on the face the ball was struck. While this seems convenient in that you do not have to wipe the face between shots as with foot powder, it would not be like hitting an actual ball. Awhile back, there was another infomercial about a similar item where the balls would stick to a target rather than tnhe club face. Not something I would buy for $29 however.
Go with what you know!
