Impact Ball Liner 3-Pack

So far so good. Played only once since receiving the product. Made a 50' putt for birdie and would have to give credit to the impact ball liner.

Unfortunately, I wasn’t very happy with this alignment aid. I have something similar and what I see a difference in is the thickness of the wall that borders where the marker marks the ball. The wall on your marker is too thick, whereas the other one that I abused has a taper down to the ball so it gets a lot closer to the line that you wanna put on your ball.

Have not seen much of a difference in my putting, I might need more time utilizing the the product, but I do like the ball marking concept. Will continue utilizing the product.
