Review on 🏋️ PowerNet 3.2" Weighted Hitting Batting Training Balls (6 Pack) - Choose Weight, Enhance Strength and Muscle, Improve Technique and Form, Softball Size, Boost Hand-Eye Coordination by Mark Powell

My daughters immediately enjoyed using them for both punch and serve power. They could feel the difference and helped teach them how to follow their swing. The only issue was the fill/weight consistency of the balls. 2 is significantly lighter and less padded. In terms of durability, they seem to be holding up well, but time will tell. Customer service is outstanding. They emailed me and asked if I would like to try their new weighted ball prototype. I answered yes, and a few days later a new, lighter bullet came. The new ball is much smaller and weighs similar to a 12 inch ball. He'll be useful, help teach my girls better contact. Overall very satisfied with the product.
