Good training aid for the price.
February 5, 2016
Momentus Golf makes a lot of golf aids and this one is very good for the price.
There are a couple other putting aids that are a bit better that are reflective and you can see where your eyes are at in relation to the ball (inside-even-outside) the line, but this one does not. Bottom line if this device was a reflective so you could see your eye position relative to the line I would have given it 5 stars but again it is a good product and if you practice with it enough you will improve you putting stroke............
Pros:Good product for the price.
Cons:Not reflective you cannot see what position your eyes are in.
