product description    
The correct swing posture is that the left arm should be kept straight and cannot be bent. Using this curved arm alarm, as long as the left arm bends during the golfer's upswing, the alarm will make a sound. The golfer can immediately know the mistake and make corrections in time, so that the left arm maintains a stable and correct posture.
