Before buying the trampoline we have read many product reviews and ware honest little confused as regards buying a trampoline traffic light. Some write that the structure is incredibly complex, while others are missing, for example, screws, etc. The structure of our 396 version was very simple and all the parts fit. We have the trampoline now already in use throughout the summer and I have to say: TOLL That was a good buy at a fair price. All who are undecided with the size, I can only say: Do not go below 396cm. For an adult, the size alone is great and the kids go with us anyway not alone pure and therefore need even a little more space. For fixing, however, we have 30cm Schraubherige from Camping accessories gekauft-> 4 pieces and everything is rock solid.
