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

Very effective tool. Great as alignment tool.

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.

For alignment purposes there are several options available: golf ball manufacturers provide alignment aids as a standard option on new orders (even custom orders) or there are several aftermarket items that can be purchased to add an alignment line, or lines to the golf ball. What differentiates this product from all the others is that it not only provides an alignment aid but it also provides an additional line that squares up the club face to an additional line on the ball PLUS a enlarged mark on the center of the ball which gives the player a mark to focus on that forces the player to stroke ‘through’ the ball instead of hitting ‘at’ the back of the ball. Too many golfers make the mistake of hitting ‘at’ the golf ball and not ‘through’ the ball and in many cases decelerating. New putter designs with Zero Torque or offset heads are difficult to square up to the intended line but this product makes alignment easy with the intended line AND squares up the club face. This product might not be as effective on longer putts but for shorted putts (under 5-7’) especially those putts with little or no movement (break) on the green will definitely improve performance.

This is exactly what is promised, a good way to make sure your putter head is squared. Been putting on aerated greens so difficult to get the ball to stay in place, negating the effectiveness. Should be better when the greens a slick.

Works good! Not what I was wanting.

Easy to use and worth the effort.

Unlike other ball markers the template moves too easily while marking. the marker also "leaks" under the template ans smears over the ball. I marks a half dozen balls and tried to be very careful with no luck. Lines are good but the smearing looks horrible. I would not buy again

I get the idea but the plastic is not rigid so it moves when drawing a line. I wish they made it with rigid plastic material. Also why can't they make it with spring attached as well like other liners.

Simple effective and quick to use.

Absolutely love it. Helps square up your putter to the ball.

👌

Good

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.
