I have owned this trampoline for a little over 2 years now and I have to say, it has held up well. We have used it with 4 adults in and it does not affect the bounce. The zipper is still working as it should. Even with terrible storms it does not move like I have seen others move. The legs are still solid even though we move it around alot. The spring cover is a bit discolored because of the environment but this obviously doesn’t affect the use of the trampoline. My kids really enjoy it and we adults have fun on it as well. I also love that it is squared, I really didn’t want the typical round trampoline. As far as assembling it goes, I would say it was fairly easy to assemble, took my husband and I about 3 hours (Installing those springs is no joke! Lol. Overall I am very happy with my purchase and I am sure that we will enjoy this trampoline for years to come!
