I am a high school coach in New England which means that we are relegated to indoor practices for weeks on end some years, this year especially. My school does not allow us to use real baseballs in the gym so I have to use compression balls instead. Every year I have to buy new balls because my past purchases usually start to fall apart day one and are completely destroyed after 2 weeks. However these balls have lasted for 3 weeks now without a single rip to any of the balls. All of the reviews I have found for compression balls have been from younger kids, not high school use. Hopefully this helps and high school coach who is in the same situation as me. I would highly recommend this product for use at the high school level, by far the best ball I have found throughout my years of coaching.
