I bought this machine because I do play tennis 2-4 times a week. Every time I pop a racquet, it cost around 12-15 dollars. For a machine that cost around 170 shipped, was a no brainer for me. Though I did my research on what buget machine that I would buy and I came to a conclusion that the Gamma X-2 came up on top. The machine seems very durable and great quality. It does its job pretty well once you get the hang of stringing.
The negative part I would say about my experience is the time it takes to string a racquet is quite long. Another is that the clamps are very rough on your hands.
Overall, its a great buget machine. If you don't mind the tension to be slightly off, this machine will do you just fine. Since this is a buget machine, stringing a raquet takes some strenght due to the clamps.
Pros: Quality, Easy to Use, Good Value, Durability
