What is there for an event, the new trampoline Ultrafit! After unpacking the assembly contrary to the dire predictions succeeds amazingly light. Well, the spring forces violently tear on the arms, but after the 75th evenly levered spring a nasty surprise: the trampoline twists as the roof structure of the pregnant oyster in Berlin and probably because of the immense overall strength of all springs together. A push back is impossible! So all springs with force out again, the whole thing from scratch. Now I have the aligned in Libra anklets complained with garden panels, so that the oscillation of the circular tube is prevented. This then works well. My son, 13, about 1.60 m tall and 60kg heavy, try out the trampoline! Now it goes to the further construction of the fishing net. Now only it is striking that his feet stuck in the wrong position and we try with 2 helpers to pull the foot links back out. Otherwise, the connection with the vertical bars safety power available! It spontaneously ensteht again the pregnant oyster and in the same second bends a one circle tube parts of the trampoline circle. So all disassemble again, back in the packaging. Collection and credit done quickly, so at least the financial loss is zero. The kids, however, are difficult to bend, one must go to the neighborhood kids to jump again. Conclusion: The pluggable trampoline frame is too weak for the size and record the costs occasioned spring forces. Otherwise, everything was there, just that the oiled rust metal arches and feet (despite galvanizing) black hands Workwear leave behind; the design is fundamentally useful; However, the sheer size and the real space opens up only after the construction. Only for a very level gardens or places to be recommended! Some springs can be pat into the pinched tube slots only using a hammer fittings (plastic hammer). One can assume that the manufacturer this size has simply "extrapolate" and has thereby relies on the theoretical powers of the plate tube.
