Product test
Our tests on the product features are conducted in a laboratory. The Resistance test checks the string's resistance to breaking. It is performed in the lab by the Canon Ball machine and checks the longevity of each string. The Strength test is performed in our labs by a charpy impact test machine. It verifies the energy absorbed by the product and its capacity to reproduce this speed on the ball.
Stockage tips
avoid extreme temperature changes and any moisture on the string. Do not leave your racket in your car boot: the temperature can rise and fall dramatically!
