EyeLine Golf Edge Rail and Quick Look Putting Mirror to Improve Your Putting Stroke – Compact Golf Training Aid for Aim, Setup & Alignment – Use Indoor or Outdoors – Works for Right and Left Handed

It's a little pricey for a plastic aide but is as advertised. It does have the two sandpaper-like grips on the bottom. It does hold it to the carpet and is especially good on the edge of a Perfect Putt mat or something similar and helps to keep it from skidding but it could easily be knocked off-line on a different surface. It would be helpful if the base was heavier or a different material- perhaps even with a rubber grip base.

Great for practice. Key is to be able to take it on the course.

Helps groove a straight stroke. Seems like a lot of money for a piece of plastic but I've probably lost that much missing putts I should have made :-).

Easy to understand and use on the practice green or at home. Builds muscle memory and confidence. Worth the investment.

Works as described

Description stated steel alloy. Arrived plastic. Should ask for a refund, just not worth the hassle.

Please give this aid a try. It will give you that Ben Crenshaw arcing stroke. You won't have to worry so much aboutthe path of your putter. See the line, feel the putt, hear the ball plopping into the cup, then stroke along the guide. That's the way topractice with this aid, as if you are on the putting green. Make it a real stroke each time, and you will be delighted at the progress of your putting. You will see more solid, center-struck putts that ROLL beautifully on your chosen line. Now . . . just learn to read greens and you will make a ton of putts.

I used to have one of these but left it at the practice green accidentally. I was very disappointed when I ordered and received a new one. It is now made of plastic, it used to be made of steel. I believe the steel was much better. It was more stable and the “ sound” while putting was much more pleasing. Pretty disappointed.
