Bullet Stroke devices can be customized by adjusting weight and length. For example, you can ask to add length to the Golf Bullet Stroke device to make it similar in length to your favorite golf club, or to add length to the Tennis Bullet Stroke Device to make it similar in length to your tennis racket. Weight can be added by lengthening a device or increasing a device’s diameter. Adding a device’s length always increases a device’s weight. Contact info@bulletstroke.com and specify the device you want and how you would like to customize it. Upon receipt of your information, we will create the new device’s dimensions (if possible) and price.
