I know such a racket in a self-defense seminar learned and decided that I absolutely must have, therefore, not wanted and ordered long. When the bat got the joy was great and they were tried at once, though I've found that they are slightly smaller than the know in the seminar learned, probably because this is a product for children. I can recommend it only for energy / stress reduction in children and adults, the risk of injury is also at a fixed strike virtually zero. Only downside is, as already mentioned in a previous review, the cable ties to the touch, if you can not pay attention because you look quite good slightly hurt.
