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.

With the increased seam length, Goff says there was actually a risk that this ball would be too rough. “Very little changes in those textures can have noticeable aerodynamic effects,” he says. The fact that the Telstar 18 has almost the same drag curve as the Brazuca, with aerodynamic properties changing at about the same speeds, is impressive. “It has to be an engineering and technical challenge,” he says.
A radically new configuration reduced the amount of panel touch points forming a smooth and perfectly round exterior that improved accuracy and control. Prior to the Teamgeist, the surface of World Cup match balls had notable differences depending on where a player would strike the ball due to seams, ridges and other imperfections where panels come together. The revolutionary propeller design of the Teamgeist minimized corners and created a smoother surface for improved play. The ball was designed with traditional colors of the German flag and was accentuated with the golden color of the World Cup trophy. 
Wilson is a classic sports company that gives you just about everything that you need in a soccer ball. This ball has a synthetic leather cover which is soft to the kick, but also has enhanced ball durability. It has a butyl rubber bladder to hold the air which gives the ball its shape and and retains the air. This has the classic black and white panel colors.
On the other hand, replicas (sometimes called training balls or gliders) are designed to be just like the official match balls but are much cheaper. Their panels are often stitched rather than thermally-bonded and are made of a different material. However, they’re not necessarily less durable than official match balls. So, they’re the recommended option for most players.
