We purchased this trampoline two years ago and have been very pleased with it so far.  The kids love it, and it seems very durable.  My husband and I do break it down and store it in-doors during the winter to give it longer life and maintain the netting structure.  It's quite easy, only takes about 45min to breakdown, as well as about the same timing to set back up in the spring.  If you choose to do this, we suggest that using a permanent marker, letter the connections so that you can re-erect it the way it was set up prior.
