Excellent product! Spins and sharpness were realized instantly! Really helps the pitcher keep the ball in the fingertips, allowing them to get the most speed and spin rate with each pitch.

Just starting to use the SpinGrip. Ball season is over for her. Going to do lots of practice. My daughter likes how it fits and forces her to use her fingers for pitching.

As a private pitching instructor I invested in the spin grips after seeing success from one of my clients. I have seen spin and snap progress at all ages. I purchased all 3 sizes and have been very happy with them all. My clients have noticed such a difference that they to are purchasing their own spin grips. Thanks for such a great product. -KMac Academy
