Fits inside my standard, low-tech, Schutt batting tee (iD 30mm), and is an upgraded tee topper to extend the life of the batting tee, or with some duct tape can resurrect a tee that no longer has an intact cup to hold the ball.

So far with these settings and Duramic TPU 95a I have hit over 1500 balls over 3 weeks and it is still working great.

Someone buy me a regulation fastpitch &or softball and I will make remixes that hold those balls better.
