all good. nice and all working as should. quick delivery
after some time using this device is notorious the difference. I feel my arm strengthened tendons. My wrist stoped hurting.
it was a little bit hard to start it, but i watched a video about that at youtube and after that it was super. it is yery cool, and it puts strain on the muscles, and not so easy to keep it moving.
funguje, OK
Schnell, gut und günstig,- so macht Einkaufen Spaß! Und der Trainingsball funktioniert perfekt. Leider gab es nur eine chinesische Erklärung, auf die man aber verzichten kann, da das Gerät einfach ist
Πολύ καλό, γυμνάζεις αποσυμπιεζεις καρπό
tudo OK, óptimo desempenho
Schnelle Lieferung, Ware hochwetig, wie beschrieben. Danke.

Once I figured out how to start it, I am impressed at the exercise my hand, wrist, and forearm get from moving this ball. To start it you "wind it up" by moving the inner wheels in the direction of the arrow shown on the wheels. Turn and hold, turn and hold the wheels until it gets wound up, then hold it in your hand with the open wheel side down, let go of the wheels, and move your hand in a small circle to get the wheels moving faster. The way the ball lights up is really cool.
