Yesterday the trampoline (the 251cm) received. It was incl. A small coffee break in 1 1/2 hours up alone but I have also used ground anchor since our first wind has fallen victim. So it's certainly in less than an hour to create. Processing is a trampoline in its price range perfectly okay. Did it then tried it myself and it keeps perfectly. Give now times 5 Stars. Should it now hold even longer without any problems, I am satisfied.
