The discdot putting aide is awesome. It is easy to use, easy to see while in the chain of your basket. I feel that it really helps with focus and muscle memory. I have been use my discdot three times a week for two weeks, 1hour a session and have gained confidence and accuracy. I am averaging 80% from 30 feet, which is an increase from 60%. The t shirt fits and feels comfortable as well. The distance marker are easy to use and easy to see as you are returning to your spot. I recommend that every disc golfer get some disc dots.
