Ok. I was skeptical about this ball...surprisingly it is bright. It seems smaller than a normal soccer ball so I measured it. Yep, 27” as stated. I wonder how long the batteries will last. I’ll update this review after the 1st pair die. feels durable. Lights upon kicking. Takes two sets of batteries to light entire ball so make sure you keep lots of replacements on hand otherwise you’ll end up with 1/2 the ball lit.
The bladder, or the inside, of the soccer ball, is also very important to talk about.  There are typically only two choices that they are made out of butyl and latex.  The higher-end balls usually are latex while butyl is typically meant for training balls.  However, butyl is much better at keeping the air and shape of the ball for longer periods!   
As a response to the problems with the balls in the 1962 FIFA World Cup, Adidas created the Adidas Santiago[17] – this led to Adidas winning the contract to supply the match balls for all official FIFA and UEFA matches, which they have held since the 1970s, and also for the Olympic Games.[18] They also supply the ball for the UEFA Champions League which is called the Adidas Finale.
The flight of the ball is accurate to the type of kick that put it into motion because of the 12 panels pieced together flawlessly. The Aerowtrac grooves allow the ball to soar through the air swiftly. The interior bladder is restricted to produce a healthy sphere full of air. The shape is retained even through heavy use and harsh playing conditions.
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
