Holabird is always efficient and offers a very good price.
The tournagrip continues to do what it is supposed to do, keep your racket grip from slipping. Some reviewers have said a grip will last for 15 to 25 hours. That has never been my experience. But it works very well in comparison to the competition. After 40+ years of competition I've had time to experience the competition, and I no longer look for a better product. This works and is affordable.
