Don has been in business for years. He's routinely portrayed as one of the most notable stringers on the East Coast, even stringing for some pros. Having grown up in Charlotte, I've encountered Don since I was 16...I am now close to 40. Having played tennis in the area since I was 12, I know a thing or two about tennis, I even sold and strung rackets as some of my first jobs. When I was really playing, I played competitively at the 4.0 level. So my point, I know tennis.
Pros: excellent equipment selection
Cons: customer service requires ATP tour card credentials
