The trampoline is really processed very well and everything fits perfectly. Also, the system in order to fasten the spring is good. Everything went quickly and only I alone had the part are in 1.5 hours.. I would, however, have been even faster if following the instructions would be how to build the safety net properly. So very important if your secured to the ring you have to the feet the bars for safety net directly install and tighten. Otherwise you have to take everything apart again. If you install the jump power, ensures that the cutouts on vault network as are the bars where going from safety net high. Last Tip: The orange ends are tightened with the small screws that power is only over it stretched and will not budge. Below the net is then attached to the holders of the springs and is good! Children have NEN huge fun and I would definitely buy it again.
