PuttOUT Devil Ball 3 Pack

By exaggerating the effect of your putter’s face angle, the Devil Ball will train you to deliver your putter back to the ball square. Due to its flat-edged impact zone, Devil Ball exaggerates the face angle of your putter at impact. It’s more difficult to make Devil Ball roll straight than a normal, spherical golf ball, meaning it’s twice as hard to hole a 3-foot putt. If you deliver a closed putter face, Devil Ball will spin erratically off to the left of the target. If you deliver an open putter face, Devil Ball will spin erratically off to the right.
