The Edge Volleyball Trainer has been a great tool to isolate our hitters so we can focus on footwork, arm swing, and how they address the setter. I have been able to take a specific group of players, like Middle Hitters, and have them focus on the hitting mechanics of a specific set and learn what it feels like to hit the ball hard. This also allows me to keep more players active during practice and limit any standing around. Very happy with this product!
