Rev up your game with the Brunswick PowrKoil wrist positioner.
I just bought this product 2 months ago.The performance of this product is really awesome, because it makes my shot steady and consistent. Our winter league just started a month ago and 2 weeks ago i shot my first 300 game, and last night i shot again my 2nd 300 in my first game and shot my first 838 (300, 279 ,259).
This product is great!! Helped my bowling game a lot.
