Unfortunately, these balls were by far the worst I've ever played! The flight behavior of the ball is not just acceptable but the bounce of the ball is absolutely atypical and bad. Due to the partially misserablen seams the ball bounces off wherever he wants ... A strong top spin game by simply impossible. Added to this is the excessive wear of the felt. After only one set of felt was from almost complete. Have also tried the second package because I have my hoped a pack with production error condition, unfortunately the result was identical. The third package I have now my Not to play (not tennis !!!) geschnenkt!
After this I take Erfahrug like back to the unfortunately somewhat more expensive, but qualitätiv worlds better Dunlop and Wilson products ...
