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!"
Much like PU or TPU for soccer ball casings, rubber is considered the best of both worlds for soccer ball bladders when it comes to striking a balance between responsiveness and air retention. Oddly enough, this balance does not actually inspire a greater adoption by either manufacturers or players, and as such, soccer balls with rubber bladders are less popular.
This particular indoor ball has all the qualities that make it ideal for an indoor soccer ball. The exterior uses a soft felt material. The panels of this size 5 indoor ball are hand stitched which makes it more durable than machine stitched panels. Its bounce is not too high which sits well with the requirements of an indoor soccer ball. It is not too bouncy or light but it flies rather well when kicked. This gives the player ample control during a session. It has a comfortable texture that’s pleasant to hold, for a goalkeeper and comfortable for footwork especially if the player is barefooted. Has a bright color that makes it visible during a game. Players can easily keep track of it, especially in an indoor setting.
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
