Actually, at first I was quite satisfied with the Kettler-Slingtrainer. The only downside was the strong loops of rope through the metal ring. In this way, the tape twists after a few workouts and causes an unnecessarily high friction, which leads to an increased training effort. Here other manufacturers have to offer much better solutions. Yesterday during training then that's happened, I've never thought possible, because you always hear that the tapes are tear-resistant and even much higher loads than those intended to be grown (in my case 82 kg) of a normal exercisers. The ribbon is centered approximately 15 cm below the carabiner. Without verher apparent fatigue. Thank goodness I ended up only on the seat of your pants. However, I do not want to imagine what would have happened if I had just performed a demanding exercise me. Therefore I forgive 1 point and advise against buying.
