I've used this product to make my putter stroke more consistent. If you drag the putter (get your hands ahead of the putterhead) this product will expose that. If you are a wristy putter, this will expose that. If you want to develop a stroke that has a firm (not tight) grip and use your shoulders and body to stroke the ball, as most instructors want, this product should work for you. And as mentioned in the article, use a flat surface or mat to putt on.
