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.
One of the main reasons but not the only reason to select this ball for reviewing is the great mission of the company. If you buy one ball, they will donate one ball to the kids of developing countries against your purchase. So, this is a “Buy One, Give One” charity model, and of course, it is a good mission where you can also contribute by buying one.
Soccer ball covers are meant to protect the construction of a ball, and make it more durable and long lasting. Manufacturers use two types of materials, mainly polyurethane (PU) or polyvinyl carbonate (PVC). PVC is the cheaper and much affordable variant, but it is more durable than PU. It has scuff-resistance, which makes it perfect for training soccer balls. PU is used for match balls, since it is softer than a PVC soccer ball and tends to respond better to contact.
This is the best ball ever made for dogs, especially large dogs who can usually rip a ball apart in a matter of minutes, like mine. This is our second one, the first one we had for over 2 years and my pit bull put so many teeth marks in this ball and it never went flat. The pump end eventually fell out and it still stayed round and would bounce. We only had to buy another one because my crazy dog liked to throw it up in the air and it went over the back fence and another dog (or kid) decided to take it home. I also like that I buy one for my dog, and a kid somewhere gets one too. I will never own another brand of ball for my dogs.
