I purchased the Knuckle It Pro soccer ball for my sons 12 th birthday in August of 2017. When I asked what he would like for his birthday he had mentioned this ball. I had never heard of it so I began doing research on the product. We had at least 4 soccer balls at home at the time so I wasn't sure I'd go with another ball. We have one of nearly every major brand ranging in price from $15-30. He had even received a $40 ball just months before for Christmas so I really didn't see the point in one more.
Changes in temperature will also affect the inflation level of the soccer ball. Extreme heat or extreme cold will alter the shape of the bladder and this will affect the integrity of the soccer ball. Although it doesn’t seem like you could reach an extreme temperature that could do this to a soccer ball, just leaving a ball in your trunk or the back of a van on a hot Summer’s day will do it.
We found that the feeling of this ball was a bit harder than other soccer balls at this price point. This doesn’t affect the performance of the ball, as the movements were accurate and authentic when struck. The weight does tend to affect the foot and ankle over time, causing a bit of soreness after continuous play. It also features a machine-stitched construction that is accompanied by an internal nylon-wound carcass so the ball has an improved level of durability compared to other soccer balls at this price point.
