I bought three and used them for juggling, shooting practice and kicking against a wall. I juggled 90,000 times in 3 months, and shot many times on goal and kicked against walls. These are very durable. I look for durability in practice balls and these are superb. I wonder if Wilson has the newer cover pattern with the same internal structure in any model of ball. It would be wise to do that for the sake of staying current. I love the feel when kicking. Variable amounts of air can be used based on personal preference while practicing. A little less air allows a more forgiving bounce while juggling.

Update (2 years post-purchase): Still love this ball and it's in its fifth season of use! I've just ordered another for our team since the fall season makes for darker and darker practices on our unlighted scrimmage field and we've come to rely on this ball so much. My teenagers use this ball at home all the time, including playing "soccer tennis" on hard surfaces and for banging against a brick wall (all of the print is long gone from the outer surface). We even took it to the beach this year. It never fails to get a reaction from people who see it bouncing around in the dark. I did have to replace one of the two lights, but they're available from GlowCity and are very reasonably priced (I purchased a couple of extra lights, just in case). I also bought a pack of 100
Machine stitched paneling and the nylon wound carcass helps to mold the shape that is inflated to a perfect circle due to its butyl bladder, which maintains its structure at all times. Using an abrasion resistant TPU exterior, the ball retains its style no matter where it is being played with. The synthetic panels are strong yet comfortable on the side of feet making it a terrific ball to practice skill-building.

Outside of PU and TPU, pretty much every other material used for a soccer ball’s casing will be specialized for either durability or responsiveness. When it comes to synthetic leather, the focus is also exclusively on responsiveness and this is by far the most responsive material used for a soccer ball’s casing. It is important to note that PU, TPU, and PVC are all often labeled as synthetic leather.

It depends on its intended use. Soccer ball casings are made from three kinds of synthetic materials. Polyvinyl carbonate (PVC) which is what most less expensive training balls are made from, Polyurethane (PU) which is the preferred ball for soccer tournaments, and a combination of the two. There are also foam and rubber training soccer balls for kids. Some kids' soccer balls are made of 100 percent thermoplastic polyurethane (TPU), which is a kind of foamy casing material so the ball is very soft. There are greater and lesser grades of each kind of material. PU-covered balls are generally softer, livelier, and have a better feel to them, and are what most people seek when looking for a optimal performing soccer ball.
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
