Quote - Jeff Coetzee

"After testing the 2nd Serve string made from 100% recycled plastic bottles, I can confidently say it is a very impressive and innovative product."

"In terms of performance, the string feels dynamic and responsive. It offers solid control while still allowing players to generate good spin. Compared to other polyester strings I’ve tested, spin production is competitive, and in some cases even easier to access due to the string’s feel.

Durability is excellent. The string holds up very well over time, which is a major advantage. There is some minor tension loss, but this is comparable to most poly strings and can also be influenced by factors such as heat and playing conditions. Overall, tension maintenance is good and the playability remains consistent for a reasonable period.

What sets this string apart is clearly its sustainability—being made from 100% recycled plastic bottles—without compromising performance. That combination of eco-conscious production and high-level playability makes it unique among poly strings currently on the market.

In terms of recommendations, this string is suitable for a wide range of players:

Advanced and competitive players looking for durability and control

ATP/WTA professionals who value consistency and spin potential

High-level juniors (ITF U14, U16, U18)

Team competition players at a high level

Regular adult players with an intermediate to advanced standard

Overall, this is a versatile, durable, and environmentally responsible string that performs at a high level.

 I would definitely recommend players to try different tensions to find their optimal setup."
