description:

when many beginners swing high balls, they often bend their left arm during the swing, which leads to frequent failure to hit the ball or unsatisfactory hitting effect,

the correct upper swing posture is that the left arm should remain straight and cannot be bent.

Using this crank alarm, the player can immediately know the error and correct it in time as long as the left arm is bent during the swing, so as to keep the left arm stable and correct posture.
