2.0 Kit - Precision Golf Ball Alignment Marker, Durable Metal, Sleek Design for Improved Aim Control and Putting Accuracy - PGA Professional Designed

I guarantee that if you buy this and use it on the course, you will make more putts than you have ever made before, and even better the ones you miss will leave more tap ins. It will greatly reduce the number of putts you make in a round. I recommend getting the metal one though. I got the plastic one and while it works great, I think the metal is even more stable. Its hard to explain, but there are less adjustments I make if I had the metal version. But I still get the same amazing results.If I had one con. It is that the pen marker marks you make take up a lot of the ball such that when you hit the ball with an iron on other shots you will get pen markings on your irons. They can be wiped off, but I would let your ball dry off a bit before using it after you put the markings on it. But even then if you hit the right spot with a lot of compression, it will still leave pen marks on your irons. You could get pen marks with just a line on the ball too.Buy this, and I promise you will not be sorry.

I was excited to get this product because I can understand exactly what it is supposed to do. Upon getting it and using it, the product seems to be made VERY cheaply. The part that holds the ball so that you can mark it works perfectly, no problems there. However, the part that you use to line up your putt is pretty flimsy and slides TOO EASILY. There should be SOME tension in that piece so that the slightest touch doesn’t knock it off the line you are putting it on.That’s the only thing wrong with it, but that is the most important piece to function correctly. I was very discouraged because I thought this would be a great product.Maybe they will fix it and send me a new one with more tension so I can update my review.Conclusion: this product is not worth the price. It could be though with some design patches.

My husband and son enjoy using this item.
