Not the finest stringgs

It’s been just 3-4 sessions since re-string. Guess I can already see the smash power reducing.

Used for 1 day

Dear team, I changed the string again for my badminton racquet few weeks back at Madurai Store. I got the racquet back on Sunday and played just few matches and string got broken again. What do you say for the quality now.? I need some quick solution for this rather than paying full amount again and getting it strung.

Hi Shirabthinath,

We are extremely sorry that the strings did not last long, we would surely look into the matter. In the mean time you can take the strings back to the store and get a replacement for free.

Please do let us know if that works.

Thank You


Badminton Racquet Restring

Hello Chia, thank you for your time in leaving us with a 5-Star rating on our product & service. We are glad that we managed to restring your racket for the best performance for you on the court. We are more than happy to share our knowledge and deliver the best service again for you next time. Please let us know if there is anything else we can improve on in the future. Thank you once again for your time and we hope to serve you again soon!



This string provides the right amount of thickness which gives an overall balance to the performance. It has both power and control while providing the right amount of durability due to it being 0.69. This string should go well with the even balanced rackets for all-rounded players. It might be a bit slippery in terms of hitting feel, might take some time before you get used to it.


Good service
