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!"
I bought this soccer ball for my granddaughters for Christmas. It arrived inflated, which concerned me. My husband inflated it with no problem and it is just fine. The ball is bigger than I thought it would be, but that is because it is a size 5 and the girls use a size 4. I didn't see the different sizes when I ordered it. It does light up very nicely and the girls love it. They got outdoor soccer nets for Christmas and I thought this ball would be great as they play late in the day. They can't wait to put it to use.
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
