I used the putting arc several years back, and found it useful, but by no means was it the quintessential answer to solving my putting woes. After retirement last year, I avidly play 5-7 times weekly, and when my putting is on, my scores are usually around par.

I could definitely provide an unbiased review for this product. Let me help out with the testing of this training aide and hopefully cut out my lost strokes on the greens.
