The Putting Mirror is an optimal alignment training aid used by many tour players and trains to improve your putting. It immediately improves your "alignment to target" and "putter-face alignment" while keeping your eyes over (or slightly inside) of the line you're putting. This promotes a better stance and stroke. The Putting Mirror gives visual feedback where your eyes, putter face, and shoulders are in relation to the shot, improving accuracy and consistency, and creating confidence on the green!
