This alignment tool is well-made, strong, and effective. However, the markers tend to fade quickly and not be waterproof. The slots for lines are too wide, making it difficult to draw sharp lines.

The product is considered easy to use and works as advertised. However, the cutouts are small and the stencils are not very clear, requiring a fine marker or metal template to achieve the desired results. Some users found it tricky to attach together and see where they are marking the ball.

This product is highly recommended for golfers, as it helps in aligning golf balls and is easy to use. It is well-constructed and durable. However, some users experienced issues with the hinge breaking and the line being slightly skinine.
