This ball has seen a lot of use since Christmas, and while that's not a good indication of how long the batteries and lights will last, my kids have been having a blast with it at night. This ball isn't like a normal soccer ball, it's more of a smooth rubber, so it won't have the same feel as a normal ball. It feels heavier to me too, but I didn't confirm that on the scale. Once or twice the ball turned off in use, but came back on after a minute. I recommend this ball as an outdoor nighttime novelty ball, certainly not a competition ball. And the 5-star rating is directly from my 8-year-old son. His words, "I love it!"
I’ve been a fan of soccer since I was 12, and choosing the right ball has always been an issue for me for many reasons ( size of the ball, its cover get torn easily, the ball don’t last long). this article had shed the light on everything you should take into consideration when buying a soccer ball, it was a very informative and well explained article it made me feel engrossed while reading it, so thanks for sharing. The Knuckle-it Pro soccer ball caught my attention, the features of this ball suits my needs as I love freekicks and I don’t really care about the brands. I’ll keep this ball in my mind for sure, when i consider buying a new ball.
If you've ever noticed, a traditional soccer ball resembles a geodesic dome building. Such as the one designed by architect, Richard Buckminster Fuller. Thus the ball became called the Buckminster Ball. Or more simply, the "Buckeyball". The design is characterized by a pattern of twenty hexagon pieces, and twelve pentagon pieces, fitted together to create a perfect sphere. The soccer ball has undergone many design changes of various-shaped panels stitched together. But until the geodesic dome-like ball, it was never quite round enough to perform right. Manufacturers settled upon the modern thirty-two panel design, which enables the ball to roll and spin more evenly and smoothly. Which is probably why it's the most popular competition soccer ball on the market today. The Buckminister-style soccer ball was first sold in the 1950s, and debuted in the 1970 World Cup tournament.
The cheaper balls only have two polyester layers on their lining. Soccer ball bladders can be made from two different kinds of materials. They can either be latex or butyl. A soccer ball bladder is a component of a soccer ball and it is tasked in containing the air that is within the ball. It also contributes to its shape and the ball’s receptiveness on the field.

The game of soccer has evolved greatly over the years and the ball has evolved with it.  In days past, defenses played with as many as six men back.  Then things changed around the 1950s to allow when many teams played four forwards at one time!  Now, we are in a period where we see (sometimes) one natural forward in a team.  The changes that have happened in the game have oftentimes been a result of the changes to the soccer ball itself.  Through its many changes, it has allowed teams to change strategies.
Select's attention to detail can be found in the ball's handy work and composition. It comes in nine different colors, including bright orange and bright yellow, which are perfect for training in semi-darkness. The 1.5mm PU cover is hand-stitched and textured for the brighter colors, adding durability. The design also aides turf play by zeroing in on control and resistance.
Size 5 is the official size for professional matches. Therefore, this ball is only available in this size. Do not use this soccer ball on concreted areas. Its unique rubber uses Puma Airlock Valve Technology (PAL) in order to facilitate proper airlock technology. This ball features Perimeter Balance Technology (PBT) which enables it to maintain impressive flight characteristics.
The soccer ball has gone through various changes just as the football game. As opposed to yesterday’s football ball that had stitches and seams and the classic black and white design, today’s soccer balls are designed with the latest technology that lets the ball bend more, fly quicker and also dip harder. Besides, they are quite soft that they let players kick the ball further without risking injuries.
Having just the right soccer ball can make it easy to sharpen your skills each time you step on the soccer pitch. Official-sized Nike soccer balls provide a realistic feel and bounce as you move down the pitch, or choose colorful Brava soccer balls to show off support for your country's World Cup team. Pick up adidas soccer balls that highlight your love for your favorite football club, so that everyone will know if you support Man U or Chelsea.

Today's footballs are more complex than past footballs. Most modern footballs consist of twelve regular pentagonal and twenty regular hexagonal panels positioned in a truncated icosahedron spherical geometry.[4] Some premium-grade 32-panel balls use non-regular polygons to give a closer approximation to sphericality.[12] The inside of the football is made up of a latex bladder which enables the football to be pressurised. The ball's panel pairs are stitched along the edge; this procedure can either be performed manually or with a machine.[5] The size of a football is roughly 22 cm (8.65 inches) in diameter for a regulation size 5 ball. Rules state that a size 5 ball must be 68 to 70 cm in circumference. Averaging that to 69 cm and then dividing by π gives about 22 cm for a diameter.
How Do I inflate my soccer balls? Soccer balls lose air pressure over time. Sometimes over a few days (soccer balls that use butyl bladders keep air pressure longer than balls that use latex bladders). Be sure to check the pressure frequently to make sure the ball is properly inflated.  Therefore, invest in a good ball pump, have a supply of inflation needles and use a low pressure gauge to measure for proper inflation. 
I decided to try to contact Kan Jam, since I was more interested in the possibility of an exchange than a return. In my experience, if a company will honor an exchange, some of the time, they won't require that you send the original product back. But I couldn't find any direct contact info for Kan Jam and decided to just open up a Return Request through Amazon. I did say in the comments that I would prefer an exchange over a return, but I
Elements of the football that today are tested are the deformation of the football when it is kicked or when the ball hits a surface. Two styles of footballs have been tested by the Sports Technology Research Group of Wolfson School of Mechanical and Manufacturing Engineering in Loughborough University; these two models are called the Basic FE model and the Developed FE model of the football. The basic model considered the ball as being a spherical shell with isotropic material properties. The developed model also utilised isotropic material properties but included an additional stiffer stitching seam region.
The most modern feature is an embedded NFC chip, which is found on the top of the ball. If you download a free app on iOS or Android, you can personally interact with the ball's exclusive content and location-specific challenges. You'll also be able to participate and enter competitions and World Cup-related challenges. Of course, you can record and upload your experiences for social media posterity.
