The ball allows you to practice rugby passing on your own.
If you spin the ball, it is designed to spin right back to you.
You or your kids have started playing rugby, they're struggling to spin or pass the ball accurately or throwing the line out into to the wrong teams hands. You can of course practice with others but when you want to rapidly improve your passing skills in your own time, this is the training tool you need.
"The key is not the "will to win" – everybody has that. It is the will to prepare to win that is important."
