Well, it really is very inexpensive - but in my opinion you realize this too! Despite several attempts oiling the part quitscht scary ... And you really have to bring a certain weight so that the very stiff suspension also evokes the feeling of "flying". My little daughter is on it and it does not happen very much - she then goes back to her dear children trampoline. So not really suitable for lightweights / small children. Furthermore, it shows that the pressure point is not evenly distributed - in the middle of it stands out best. At the edge of the jump action can head off enormously. This is not the case with expensive equipment. I'll be there but probably invest again in a good trampoline. My Conclusion: For the price it is absolutely properly adjusted. The processing makes a solid impression. However, one should also note my above points.
