We promised our children a Zip Wire for Christmas and eventually got it up by Easter, it took an hour or so to set up, we recommend wooden blocks behind the wire to protect the tree and two people to get it up right and secure - but its great fun the whole family have been on it and its strong enough for adults. The fixings are a bit week but stronger ones can be bought cheaply in local diy stores for extra strength. We've had it up a few weeks now and gave it a spray of silicone to get the thing going faster again, I guess wd40 would help every month or so. But a top toy for the garden, all the children love it. A swing attached to it helps - you need a lot of strength to hold on to the top bar - especially little ones. Enjoy hopefully for many years to come.
