These are used in international level matches and top league matches like UEFA Champions League, Italian Serie A, English Premier League, Spanish La Liga, Bundesliga, Major League Soccer. Not only these but also all the tournaments approved by FIFA. So you can easily understand that these are the highest quality balls with the highest level of air retention, shape, water absorption, trajectory, curve, and performance. Otherwise, FIFA would not have approved these balls.
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.
