This ball uses installed sensors in it. These sensors collects data and shares it to your iOs and Android app via Bluetooth. Additionally, it gives you tips on how to improve your performance and compares kicks to keep track of your progress. Minimal maintenance is required as a single charge of this smart ball takes an hour and will facilitate about 2000 kicks each week. Its casing uses PU and the bladder – butyl. This ball has 32 thermal bonded panels hence increased control.
Our main intention of finding the official match balls was to help you find a solution which is good in quality, and you can use it for league plays. The process was tough we must say. Not all the replica balls have good quality. That is why we were very choosy in the process. We filtered the balls not only based on our experience but also based on the experience of other users.
You just can’t avoid the name of Lionel Messi in the soccer world anymore!  And with this ball, Adidas promises to make you like Messi.  Like the last ball, it has a nylon interior and is machine stitched.  It also has a butyl bladder so that it retains air better.  While this ball is surely a good option, it is a little pricey.  The name alone probably drives it up, but if you’re a Messi fan it may well be worth it to you!  And oh, it also looks like a ball from Pokemon!
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.[4] Some premium-grade 32-panel balls use non-regular polygons to give a closer approximation to sphericality.[12] 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.[5] 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.
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!"
How Do I inflate my soccer balls? Soccer balls lose air pressure over time. Sometimes over a few days (soccer balls that use butyl bladders keep air pressure longer than balls that use latex bladders). Be sure to check the pressure frequently to make sure the ball is properly inflated.  Therefore, invest in a good ball pump, have a supply of inflation needles and use a low pressure gauge to measure for proper inflation. 
The fact that this ball was not only tested but used in 2016 Euro qualification matches makes it a trusted choice. Its graphics are minimal with the majority of the surface being white in color. A hint of red and silver streaks breaks the monotony of the white yet maintains a simplistic appeal which appeals to the simplistic users. The graphic designs go against the panels which gives it a unique appeal. Its casing uses 100% PU leather and the panels are thermal-bonded which makes the surface smooth. Its bladder uses butyl material which improves air retention. The surface of the ball provides lower water absorption which contributes to its durability and gives it a better feel.
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
