EyeLine Golf Impact Ball Liner 3-Pack with Marker by Hank Haney - Easy Ball Marking Stencil for Accurate Putter Face & Target Line, USGA Legal, Precision Putting Alignment Tool Used by Tour Players

Since I’ve used this product my all round game has improved, both driving and putting accuracy. And now using pick and place on fairways is also helping.

Looks good not use it yet on the course if it helps my putting great

Ok but not top class product

Not for me. Didn’t help.

Works great, but it's a little pricey for a piece of injection-molded plastic. I absolutely love how this looks when you're standing over a putt because of how square it looks, and some friends of mine have asked where to get one for themselves. The 3-pack is great if you lose stuff that goes in to your pockets like me. The marker it comes with is awful, so I recommend getting an ultra fine tip sharpie if you want to make crisp lines. It does cause some of the line edges to bleed a little bit when you pull the stencil off the ball, which is a common annoyance I have with pretty much all marker stencils.

Real review here , I kept seeing this product on tik toks and Facebook and Instagram. I was skeptical because I have a few similar products but none like this. This product completely changed how my girlfriend was putting for the better. She can actually see how the face is supposed to be square now and how to aim her putts. This was the best money I’ve spent trying to teach her how to putt. If you struggle with face alignment please try this. It’s amazing.

Works great making more putts

I really like the concept, so I brought a sleeve of three. I’m a good putter but have alway struggled a bit with alignment. After a few rounds I have to admit this device really helped me. Allowed me to get the ball on line and tracking toward the hole. Quality is good, but overpriced for what it cost to product. Nevertheless, I would recommend. It certainly helped my issues!

Feels like a more precise lineup when putting your ball on the green.
