This soccer ball is awesome!! I bought it as a birthday present for my eight year old son's classmate. Both play soccer together, too. Well this ball was a hit!! My son's friend loved it! In fact, he brings it to soccer practices and the entire team uses it during the scrimmage at the end of practice when it starts to get dark. Other moms have dropped it into their Amazon cart to buy for their own sons and I have as well. I chose this ball based on the reviews as well as the fact that it included extra batteries (the ball already comes with a set of batteries) and a pump.
Size 5 is the official size for professional matches. Therefore, this ball is only available in this size. Do not use this soccer ball on concreted areas. Its unique rubber uses Puma Airlock Valve Technology (PAL) in order to facilitate proper airlock technology. This ball features Perimeter Balance Technology (PBT) which enables it to maintain impressive flight characteristics. https://www.youtube.com/watch?v=j2Xn84L3Kcs
