The ball weighs after inflation well 290 grams, so a good 10 grams more than the regulations actually provides.
I it but only as a hobby use that is not really relevant topic for me.
In the official game mode the "overweight" but already a NoGo could represent.
The ball is meticulously crafted, the seams are all closed and have no protrusions.
The material feels very good and the necessary traction is provided.
Even after several intensive indoor units of the ball still looks like new.
I would be completely satisfied if the price would be a bit too high for my feeling.
I therefore give four stars.
I hope this review could assist you in your purchase decision ....
