Defective piece
I have tried my friends product that he got from US and this was worthless as compared to that.The rotator ball was not firm and hence momentum never sustained.

Rotor unstable, does not work.
The rotor was not stable, unable to sustain rotation. This is a cheap Chinese Powerball which does not work.
