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.
Still, despite how impressive the materials used for the soccer ball are, Adidas is not done providing one of the best products available. For instance, this ball uses thermal bonding instead of either hand or machine stitching. This has the advantage of allowing the ball to fly truer as well as resisting water better. On top of that, some sellers even have balls with embedded NFC chips, which provide all kinds of valuable feedback information on you play.
Now let’s talk a bit about what is it that they are made of and sizes and it’s importance. Soccer is the best way to learn physics as you learn to control a ball’s movement, all the while studying the force you need to exert to get to that optimal point. Specially for a professional player or someone who is on the path to it. They must know ins and out while they learn to control it.
Adidas spared little expense with this soccer ball and made sure that the materials used could pass almost any standard for grass fields. First, the casing is made of polyurethane, providing a great balance between responsiveness and durability-though they further increased the responsiveness with 3D textures. The bladder is made out of butyl, so you will not have to worry about constantly reinflating it, while the ball is lined with soft and water-resistant polyester.
Today's footballs are more complex than past footballs. Most modern footballs consist of twelve regular pentagonal and twenty regular hexagonal panels positioned in a truncated icosahedron spherical geometry. Some premium-grade 32-panel balls use non-regular polygons to give a closer approximation to sphericality. The inside of the football is made up of a latex bladder which enables the football to be pressurised. The ball's panel pairs are stitched along the edge; this procedure can either be performed manually or with a machine. The size of a football is roughly 22 cm (8.65 inches) in diameter for a regulation size 5 ball. Rules state that a size 5 ball must be 68 to 70 cm in circumference. Averaging that to 69 cm and then dividing by π gives about 22 cm for a diameter.
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.
This ball has seen a lot of use since Christmas, and while that's not a good indication of how long the batteries and lights will last, my kids have been having a blast with it at night. This ball isn't like a normal soccer ball, it's more of a smooth rubber, so it won't have the same feel as a normal ball. It feels heavier to me too, but I didn't confirm that on the scale. Once or twice the ball turned off in use, but came back on after a minute. I recommend this ball as an outdoor nighttime novelty ball, certainly not a competition ball. And the 5-star rating is directly from my 8-year-old son. His words, "I love it!"
