If you want to waste your money... The performance of those strings are about 20% lower comparing to any other strings (Yonex).
Awful awful awful junk...I can't stress that enough. There really isn't much Eagnas has that is really good. I think the only thing I bought that was worth getting from Eagnas was the string mover. Even the machine calibrator I got is not terribly useful. Its hard to see the markings and tell the tension.
