This large black baseball velocity puck is designed to help increase your moment of inertia (MOI) during hitting, which can improve your swing mechanics. I have used it for one season, and it remains in good condition with normal signs of use. The puck is a training aid that can be integrated into your batting practice to help develop stronger, more consistent swings. Please refer to the pictures for detailed views of its current condition. This item is sold as is, and is suitable for anyone looking to add a training tool to their baseball routine.
