The trampoline was built on a slightly uneven ground. The instructions have been created quite clearly and as an additive is a Übrungsanleitung that presents various jumping exercises. At first I did but then wondered how many parts out of the box appeared. Recommended the construction is for two, because all alone but takes quite a long time (about 90min). Built the whole looks then but a bit smaller than I thought before. For children, the trampoline to the usual critical points is well protected. Even for adults (with a test weight between 70 and 90kg), the trampoline is strong enough. However, it has not so much jump freedom as an adult because of the size of the jumping surface. For the fitness is still very good and easy on the joints. A tarpaulin must be ordered separately, which is unfortunately not there. An attachment to fix the trampoline at the bottom is not included. By and large, you get offered for currently 129 really good quality.
