I just wanted to pass along a quick note to inform you that the Check-Go units have become a "big hit" for my daughter's high school golf team, La Reina H.S. in Thousand Oaks, CA. The kids are so convinced that the units give them a competitive advantage that the coach has made it mandatory for each player to mark their ball prior to the match. The school is ranked #1 in the county, so their opinions are not hollow, and have translated into great play on the course.
Aside from the check-go units, the two piece golf balls we purchased have also been a roaring success. The kids feel the balls give them greater distance, and every one of the balls is perfectly marked so the kids ensure themselves of proper balance when putting.
The coach was getting a bit concerned when his supply of golf balls was dwindling this past week....hence the additional 5 dozen ball order I placed yesterday. You make a great product that truly works. Keep up the great work!
