Manufacturing defect? 1

Already on arrival, cardboard no longer resembles anything, crushed an emerging side by side.
I said to myself "this is only the cardboard."
But by opening the gyro box, I realize that he has one of her rings cut maintainers, and this cut, the tips are not in the same axis.
I "as the rotating part is not affected."
But it is not finished, the axis of rotation is not perfect (which generates noise and rapid loss of speed) and the minimum of grease or oil applied on the parts of friction was not respected ( stalling again).
So the desired effect does not last more than 5 seconds to 30 seconds of preparation, which is not much fun either "worth it".
In short, TOBAR to banish.
