When it is about quality, these are almost same as premium match soccer balls but obviously not the same. To be exact, you can say official match soccer balls are positioning between premium match balls and training soccer balls regarding quality. That means these balls also offer an excellent level of air retention, shape, water absorption, curve, and performance. Although usually, they are not as durable as training balls but as a whole, they are very much durable.
I purchased the soccer ball for my son as a gift. It came deflated so we filled it with air before boxing it. Upon opening it, it was deflated. It only held air for a few hours. I contacted the company and they immediately shipped out a new one without hassle that is holding air just fine. (I was very pleased with how prompt and pleasant they were!) It lights up very bright when hit or bounced and turns off on its own after a little while of not being hit or bounced. My kids all love it and play with it nightly. It is not stitched as a real soccer ball is, but is more of a heat fused soft plastic. It holds up just fine though to my 13 year old soccer player's kicks. We are all enjoying playing with it and happy with our purchase.
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
