When a player spins a ball during training, we can use our app to record the position of the hitting ball, the initial speed of the ball, and the position of the ball after entering the net. To increase the probability of hitting the banana ball.
If you have any questions, you can either leave a message or send the questions to our email address.
We will answer them for you in the first time.
