Great idea, unfortunately very imprecise manufacturing

The idea of ​​this foldable trampoline is wonderful. It can be very nice and small to pack in a bag and it is reassembled within minutes. Unfortunately, the build quality leaves (at least our trampoline) but wish to extreme left. The trampoline remains after unfolding simply not open but works already at the slightest touch back together, despite the supposed safety mechanism. At least our trampoline has probably not undergone quality control in Hudora. After a long search we have identified as the cause of the 0.5 cm long to individual parts of the tubular steel frame that have prevented the security mechanism of engagement. We decided nevertheless for keeping the trampoline and let reduced accordingly by a metalworker the frame parts. Now it works fine and Securely, as per description also should. Unfortunately, after a few circumstances for us!
