The Krafttrainigsreiz is even given, but it is much weaker than the right paddle, but I did not want too.
If you remove the bottom hand strap and fixed only by finger loop the paddle on his hand one gets on the wrong hand position during immersion immediate feedback by losing the paddle.
Overall, however, you should still say the paddles generally are not for beginners, you should already have a reasonably clean technology before you start with the paddle and then only dosed in training use.
When you will observe this have a lot of fun with the paddle!
Therefore 5 of 5 stars
