When I came across Breakbuster technology at the PGA merchandise Show, I can honestly say having never seen this type of technology, I was rather skeptical. However, after experiencing it myself and then, coming back the next day to see others trying the Breakbuster technology, I was very satisfied with the results. Breakbuster technology is easily learned & repeatable. It's certainly worth giving it a try and trying to improve your putting.
