The Brunswick Bionic Wrist Positioner offers several wrist cup and lateral positions to best suit your game. The extended version gives support and assists in developing a more powerful ball roll. This positioner is is made of durable aluminum materials that make it lightweight and comfortable.
He keeps telling me how much he appreciates having the new wrist guard and that he can now HOOK the ball. Great product.
This device took my game from a 130 avg to 170 avg in about 4 weeks. Last week I threw a 588 set using the Bionic. I have more control of the revs and break point. This device runs small, I ordered the LARGE and my wrist in the area the strap goes in 9.5 inches. It works but it is not optimal, I wish I would have ordered the XL.
I lost the retaining wire and am going to improvise until I buy another. On the next one I will fold the end of the strap and sew it to prevent the wire from falling off.
