Just got the Smart Ball a couple weeks ago. I've worked with it and find it very helpful in developing "the" proper golf swing. Strongly suggest you use the online training videos from Tour Striker as you learn how to use the Smart ball on different clubs. I like how it helps me develop better habits with full extension at finish, eliminating my chicken wing. A simple device and you will get the hang of it, if you practice on the range, or even at home.
