Review: Finally a line you can see - Great product
Review: Worthwhile ball liner - I use the line on my ball to line up both my putts and my drives. I was finding the thinner lines were not enough when putting, but this item produces a thicker line, much easier, and I have found it helps me to line up the putt much better.
