This is a great invention. Used correctly it must be one of the quickest ways to develop a great plane and "feel" the shape of a good swing. However, an occasional go can be disastrous to your game.....I know plenty of players that swing it well but not the one plane explanar way; if they use it, it can mess up everything. I love the idea and would happily buy one......could be a painful process.
