I purchased this but stored it without using it much. ① Visualization of the Strike Zone The strike zone is visible as a frame, and since it doesn't move like a catcher, you can practice with the awareness of throwing the ball within the frame, whether you like it or not. ② The width of the frame is the width of home plate + the width of one ball on each side. By having a margin of one ball's width instead of just the width of home plate, you can practice aiming for the edges of the strike zone. ③ The angle of the frame can be changed. By being able to change the angle, it can also be used for practicing slow balls and breaking balls with angles. Be aware of the depth of the strike zone and practice pitching while viewing it three-dimensionally, not just on a flat plane.
