Beats other popular brands

I bought this string for one of my two racquets roughly 3 years back. Strung it to 26 tension. To date, the string is intact and the power seems to have diminished only a bit. The strings, surprisingly, are Made in the US.

Super Powerful

Best strings in the market

I have used Li Ning top shelf strings with 35 lbs on my top of the line yonex power racket with aerodynamic frame. It's nothing compared to this string from decathlon, I like the texture, quality, and shot sound from this string. This string has a matte sort of finish, unlike the glossy finish of Li Ning, even though people prefer the sound of Li Ning and Yonex strings, I feel this black 990 from decathlon produces realistic sound. Other brands make loud sound on each hit which makes the game distracting.

Hello Sandeep,

We are really sorry that you faced such an issue. We would like ask you on which racket did you put the strings and from where did you get the stringing done, like from Decathlon or outside Decathlon.

Please reply to this so that we can serve you better.

Good product

Control is good, repulsion power is good. Overall its a good string that can be at par with yonex,li-ning,victor strings but I don't find the hitting sound good, a bit dull when you hear it for a .66 gauge string. I leave at 4 stars due to disappointment from hitting sound.
