The $40 Putting Mirror That Fixed My Aim (EyeLine Review)

I bought the EyeLine Putting Alignment Mirror because I was missing every 4-foot putt to the right. Not sometimes. Every single one. My playing partners started aiming me left, which is the golf equivalent of your friends giving up on you.

The mirror costs $39.95 on EyeLine’s site, or around $54-$60 on Amazon depending on which size you grab. I got the small one. More on that decision later.

Three weeks later, I am making 4-footers again. Not all of them. But enough that my buddies stopped aiming me left.

Here is what happened.

What It Is

The EyeLine Putting Alignment Mirror is a flat acrylic mirror, roughly the size of a tablet, that you lay on the ground behind your ball. It has alignment lines for your putter face, your eye position, and your shoulder line. It also has two slots cut into the surface that work as a gate drill. You stick tees in those slots and try to roll your ball through them without hitting the tees.

That is it. A mirror with lines and two holes for tees.

And somehow, that is enough to fix your putting.

The Problem It Fixes

Here is the dirty secret about putting. Most of us cannot aim. We think we are aimed at the hole. We are aimed two feet right of it. We have been doing this for years and nobody told us because nobody wants to hurt your feelings on a Saturday morning.

I was one of those people. I would stand over a 4-footer, feel completely square, and push it right every time. I thought my stroke was the problem. I spent a month doing stroke-path drills with a putting rail. Did not help at all, because my stroke was fine. My aim was broken.

The mirror showed me in about ten seconds. I set up, looked down, and my eyes were a full two inches inside the ball. That shifted my perception of the target line. Everything I saw was a lie. My putter face was aimed right because my eyes told my brain that right was straight.

That is the value of this thing. It does not fix your stroke. It fixes the thing that makes your stroke irrelevant.

How I Used It

Five minutes a day. That is the whole routine. I set the mirror on my living room carpet, placed a ball on the line, and worked through this sequence.

First, I squared my putter face to the line on the mirror. You look down, match your leading edge to the printed line, and see what square actually looks like. For me, this was a revelation. What felt square was open by about 3 degrees.

Then I checked my eyes. The mirror reflects your face back at you. There is a line on the mirror. Your eyes should be over that line. Mine were not. I adjusted until they were.

Then I rolled putts through the gate. I stuck two tees in the slots, slightly wider than my putter head, and tried to roll the ball through without clipping a tee. If your putter face is even a degree off, the ball hits a tee and ricochets sideways. Instant feedback. No guessing.

I did this for 5 minutes every morning for three weeks. By the end of week one, my eye position was consistent. By the end of week two, I was rolling putts through the gate 8 out of 10 times. By week three, I played a round and made five putts inside 6 feet that I would have missed a month earlier.

What Real Users Say

The mirror has 256 reviews on EyeLine’s site averaging 4.93 out of 5. On Amazon, the classic version sits at 4.5 stars across more than 2,600 reviews. Those are strong numbers for a piece of acrylic.

The praise is consistent. People say it fixed their eye position immediately. One reviewer on EyeLine’s site wrote that it “helped line up my stance immediately.” Another said it showed him “how much my eyes move during my stroke,” which is something you cannot feel on your own.

On Reddit, the sentiment is similar. One r/golf user said that after buying and using one, “my putting improved significantly.” Another called a putting mirror “the best thing I ever did for my golf game.” That is a strong statement from a crowd that does not hand out compliments to training aids.

The complaints are real too. A YouTube review from Glen Haynes pointed out that the mirror “scratches easily” and is “sorely lacking in instructions.” He is right on both counts. The acrylic surface will scuff if you toss it in your bag without the carry pouch. And the included instructions are basically a single card. You will need to go to YouTube or EyeLine’s site to figure out the drills.

Small vs Large

EyeLine sells several versions. The small Putting Alignment Mirror is $39.95. The Classic Mirror (Large) runs $59.95 on Amazon. There is also a Groove version with a built-in stroke path guide, and a Groove Plus that includes indoor putting posts, for around $79.95.

I got the small one. It fits in my golf bag. The large one is nearly 2 feet long. It works great at home but you are not bringing it to the course. The small one I can toss in my bag and pull out on the practice green before a round. That matters, because the whole point is building a repeatable setup routine. If the mirror lives at home, you only use it at home. If it lives in your bag, you use it everywhere.

One EyeLine reviewer said the same thing. He owned the large mirror, loved it, but kept forgetting it in his locker because it was too big to carry. He bought the small one to solve that problem. “No excuses now,” he wrote.

The Verdict

The EyeLine Putting Alignment Mirror is the best $40 I have spent on golf. Not because it is fancy. Because it is honest. It shows you exactly what you are doing wrong in the time it takes to look down.

If you shoot in the 90s and three-putt twice a round, buy the small mirror. Do the gate drill for 5 minutes a day. You will see a difference inside two weeks. If you are a single-digit handicap looking to dial in your start line, same answer. The mirror does not care about your handicap. It just shows you the truth.

If you are considering the $15 knockoff from Amazon, I get it. Save money. But the knockoffs have softer acrylic, the lines are printed less precisely, and the gate slots are often misaligned. You are buying a precision tool. Buy the precise one.

The EyeLine Putting Alignment Mirror is not sexy. It is a flat piece of plastic. It will not impress anyone when you pull it out. But it will fix your aim, and your putting will improve, and nobody cares what your training aid looks like when you are rolling in 6-footers.

Buy it. Use it. Stop missing putts to the right.
