Finally got to see the prism in action. Girl I used to coach showed at our tryouts and had one. Dad told me in the parking lot before tryouts that it was a fire stick. She was never a strong power type hitter. We were throwing front toss and her first couple hits weren’t much. Looked like she hitting of the end of the bat. She finally got her timing dialed in and started smashing the ball. It looked effortlessly. I was pretty impressed. Had a unique sound and looked like lots of pop. Wish I could’ve tested it myself. DD is drooling over one now
