Improving set up and consistency are keys to good putting!
The Mentor Putting Mirror is a simple, portable mirror which can be used indoors or out to improve your set-up, alignment and path - three crucial elements of putting. Simply place the Mentor Mirror on the green or on the carpet, and set a ball in the cutout at the end of the mirror.
Proper set up to the mirror shows your eyes directly over the target line and your putter face perfectly square. As you stroke the ball, the mirror works as a guide for your putter path on the backstroke and throughstroke.
Carry it in your golf bag to use during warm up before you play, and you will quickly develop good alignment and visualization, while working on sound putting mechanics.
