PAR Perfect Putting Mirror “Tour Proto” 3rd Gen Combo w/Shoulder Mirror- (Right Handed)–#1 PGA Tour Putting System- Ball Lies Directly On The Putting Surface- High End Quality Putting Trainer!

I know for a fact that this is the mirror Harman was crediting in his press conference through a photo of him at the Rocket Mortgage practice greens a few weeks before the open. Bought this and after a couple days of practice had one of my best long putting days ever(6 birdies). The guys at the company are super responsive and helpful with any questions or tips as well as they have a ton of instructional videos on youtube. Its a little more than the avg mirror but so worth it for all the extra feedback and quality.

Great quality and really helps with alignment and keeping the eyes over the ball. The shoulder alignment option is a must !

Great putting training aid

The mirror is great for checking ball position relative to the eyes. The shoulder board is actually pretty good too. I think it costs too much, but it's a good tool.

Although I believed this item was a bit pricey, I find that it is very effective in helping me to develop an accurate and consistent putting stroke.

Improve your putting technique with that slight arc for that center / square contact.

This thing is really good! Thank you very much for your genius invention! I can control the putter up and down based on it. Especially when I looked through the mirror to see if my left eye was just above the ball and if my shoulders were parallel and balanced. And only in this way , than I can have a good backswing arc and the correct launch direction. Thank you again!
