I purchased two of these balls for personal training and pick up games. The balls felt a little light, but the touch was great.Unfortunately one had a full blow out, in the first game, as seen by the attached photo. I don't know whether this happened when it was struck or after hitting the post, but this seems a bit fragile for a soccer ball.The second popped a few stitches in the same game (after replacing the first). I have included a picture of that damage, as well. This damage occurred in two places on the ball. The ball maintained its integrity, unlike the first, so I did not realize the damage until after the game.I am, by no means, a super soccer player, so I would have given this review one star because of these failures. The company answered my inquiry about the warranty, indicating that these were limited beta versions of the balls and that they would replace them with the new completed production design. That response earned them a couple more stars from me.Once the replacements arrive and I have a chance to test them then I'll update this review accordingly.Update 1: The replacements are on their way, but I have updated pictures for the second (black and white) ball, which has now suffered the same blowout damage as the first. I will update again once I have a chance to test the replacement balls.Update 2: I am immensely pleased with these replacements. I have used them for several games and practices and the latest photo that I uploaded show they are much more durable than the initial versions.I'm glad to see that this product now ships the same ones I received as replacements.I love the weight and touch of these balls. The odd weather this year has given me a chance to try them in varying conditions. The texture gives a solid feel whether wet or dry, hot or cold. They don't need to be broken in, like other balls do. Many other balls are excessively sticky, which can be dangerous when controlling the ball in traffic or on the run. These have just enough grip to allow easy touches, but won't grab your boots and trip you up.They have held their pressure consistently for weeks. I believe this latest picture will show a pair of small parallel scratches, which is the most wear these have shown to date. Those scratches happened when the ball collided with a bench next to the field, where I was playing. Rather than poke through the material, the impact simply made a cosmetic mark.I plan to buy more of these to have on hand for practice.
