CRESTGOLF Flat Golf Balls Two-Tier Driving Range Ball Golf Training Auxiliary Ball Flat-Shaped Golf Practice Ball 5

It is used to practice putting technique. A normal golf ball is round, this ball is flat. If your putter pushes the ball with uneven force and incorrect posture, the ball will wobble after being pushed out. So you can exercise whether the putter's action is standard and whether the strength is uniform.
Inaccuracy can make it wobbly, roll on curves or fall sideways, long practice helps end putt one hole at a time
You can see from the rolling path that your swing is correct, Unlike other training aids that force you to maintain a bird's-eye view to determine your roll path, Pill makes it easy and quick to see how you're rolling, forcing you to hit the ball and center it on the face
Curved sides increase precision, performance and additional training capacity
