Bruce Fleisher clearly indicates, "The Terris Golf® 'Competition Series' is a must for all golfers that are interested in the long-term protection of many of the structures of the hand that can, and do become affected by playing golf, and should be used by golfers of all ages. The Terris Golf® 'Training Edition' is essential for practice use, as it also has the ability to absorb much of the shock experienced by repetitive ball striking at the driving range."
