Of course, this putting ball can't hurt. It is designed to help you hit the ball square and straight, and it wobbles if you are off, even a little bit. I can see how that works when I practice. It has an arrow on it, so you have to hit it square with the arrow. I have been using it on a putting mat so I can line it up with the putting line. It does open to allow for changing the weight of the ball, but I'm not sure why I would do that -- it seems fine as it is. The instructions and text that come with it need some translation improvement by the way. The ball does require me to bend down and set it up so that it is straight at the hole. If the ball is not aligned it won't give a true response, so that gets old. It is not an expensive tool, so it might be worth trying to help you make the putts.
