Great Device To Improve Your Aim
July 28, 2010
This device works exactly as advertised and you get the kind of feedback that can make a difference. I have kept spreadsheets of my shots during the time that I have used it and can say that my accuracy has improved significantly. Use it for center ball hits as well as the various off center ball English applications. A great product at a great price that I received quickly from the nice people at Ozone Billiards.
