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!"
So it is now clear to you that you won’t have to worry about the air retention capability, durability. Now, how good is the playability? Well, in terms of rebounding, this ball performs almost like a standard ball but obviously not exactly like standard balls. Having said that, we must say the rebound is enough for recreational play and practicing purpose. You will also find this ball a bit heavier than standard balls during the shots. That is why we don’t suggest you use this option for tournament play.
