The Swing Stick is not to be used as sports equipment for added thought Sortart because he does not have enough flexibility in the oscillators and also has a very ungüstige weight distribution. This has the effect that after the swinging, while blocking the ringing after three seconds is over, but that would take at least eight to ten seconds. When swinging it makes strange noises clack, is not well in hand because the handle is shaped very chunky and angular. The DVD is not running in the player and the poster is an A4 sheet. The price is not high, but the unit should be to use at least what the Swingstick determined not. The postage for the return is by a multiple higher than the Kaufpeis, which simply means kloppen or divert the part in the bin. I am only surprised that quite often positive reviews, maybe it is because that most of the what will happen to it basically as a part use garnicht know.
