EyeLine Golf Putting Alignment Mirror, Portable Practice Putting Trainer Aid, As Seen on PGA Tour, Made in USA, Use Outdoors or on Indoor Putting mat

Very helpful for your eyeline and squaring up the putter face.Simple but highly effective.

Great product simple to use.

Pretty much like it is described - for me I would have liked to see it a little longer but that said it works as it should.

it is extremely helpful to develop a consistent stroke which eliminates the push/pull stroke (if you follow the instructions).

Very helpful! Would recommend

For the longest time, I have had an issue cutting across the ball while putting. This created spin and all sorts of alignment issues, so much so that I couldn’t really feel what taking the putter straight back felt like.After a few minutes with this on the putting green, I felt so much more confident! It’s exceptionally easy to use, all you need to do is ensure your eyes are over the midline and you are taking the putter back on the straight line. of course, make sure you have it lined up correctly.Before my most recent round, I spent 15 minutes with this on the putting green. During my round, my putting was markedly improved! I felt much more confident over the ball and made more putts on the day.I highly recommend this to anyone looking to improve their game and save some strokes while on the green.

Uncovered 2 flaws with my set up, my eyes were not over the line and my shoulders were not square to the line. I have the eyeline with the optional shoulder alignment mirror. I think the shoulder mirror has uncovered my biggest flaw that I didn't know I had. For some reason I have to move my left toe just forward of my right to get my shoulders to line up. After using this on my putting matt at home I've started to get my eyes over the line and move my left toe just slightly ahead of my right and I'm sinking putts that I've often missed before. I'm pleasantly surprised what this inexpensive training aid is doing for the weakest part of my game.

I would recommend getting a chalk line with this so you can guarantee you have the mirror dead on your start line (they're only like $9). With that said though, the mirror itself can get the job done on its own just fine--you just need to take more care lining it up.The mirror surface itself is quite clear and provides immediate feedback: You either look down after addressing the ball and see you're lined up correctly and your putter face is square, or you look down and see your alignment needs work. That's exactly what I got it for, and just 5 mins with this before my round gave me some extra confidence on the greens. Looking forward to grinding it out over longer practice sessions.I also like that it comes with a protective case, but one thing that concerns me is how long the mirror finish is going to hold up during use. Especially on damp mornings when sand on the greens will stick to the bottom of your putter, I fear that over time scratches from that will render the mirror useless. I keep a small towel in my back pocket to wipe my putter off between putts to avoid this, but that's more-tedious work than I thought I'd need to do before I made my purchase.Update: After using this several times now, something I’ve come to dislike about it is how slick it is. I like to set my putter down behind the ball while I get my feet set, and when I do this on the green itself the friction from the grass keeps my putter from sliding around. Not so on the mirror. That’s not only distracting, it’s annoying to because I try to go through my pre-putt routine each time I make a putt with the mirror. That my putter slides around on it gets me out of routine.
