This is the 4th one we've ordered! This is a tough ball that glows very brightly at night and comes with an extra battery, but we haven't had to change batteries after 2 summers of playing with it. Whenever my kids brought it out during our outdoor, night-time, community concerts, all the kids wanted to play with it and tons of parents came up to get the information on where to get it. I had originally ordered it so that my son could still see the ball at the end of his fall soccer practices, since they play on a field without lights. Now it is the favorite birthday present to give to all of my kids' friends (ages 7 and 11).
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
