I started using my 4 more yards golf tee on 4/3/13 and used it through 6/8/15 I play 18 holes of golf four times a week and estimate that i hit the tee over 2300 times. A really amazing product. The tip of the feather broke off and I retired the tee. Joseph H.

I just got the shipment and just want to say thank you!! I really believe im hitting farther with this tee and gain alot of distance from it. Its truly the best tee i ever use. Greatly appreciate your support!! Thank you" Kevin Kim 2014 tour
