Not without a reason this basketball has been chosen as the official game ball by many (mostly European) organizations. As of season 2010/2011 in Germany it is the official 1st Division Beko Basketball Bundesliga game ball. The Spalding TF-1000 ZK Pro is a high quality product which has been available throughout the global market for quite some time now and has found a lot of supporters, from recreational players, semi-pro to pros. Some players of mine have been using this ball for years and they still enjoy playing with it and won’t trade it for any other basketball. When doing scrimmages, this is the only ball they’ll accept for playing.
