I durchporbiert many balls, but this one is my absolute favorite. The balls are very hard, you can build a quick and aggressive play with them. I also have the feeling that you get the pressure more upright than other balls. They can use before they have any more bounce long. Therefore, clearly 5 star and a buy rating for all tennis players. (But tennis newcomers might have a little trouble with the ball, because he takes a lot of strength and can be very fast.)
