This is an okay trampoline. It was a pain to assemble. Don't follow the instructions...use your logic! It seems to be made sturdy enough for the most part, but the plastic caps that hold the netting on the tops of the poles are the absolute cheapest plastic you can imagine. I have disposable leftover containers in my kitchen that are made of higher quality plastic than these! They don't stay in place and I do not expect them to last, so I am already figuring out how to rig something better. Basically, if you need an affordable trampoline and are prepared to deal with a few complications, this is not a bad purchase. However, if you have the means, you might want to buy a better brand.
We have loved this trampoline so far! I spent a lot of time comparing trampoline sizes and prices and this was the best overall deal. The shipping was free and it arrived within three days! It was not difficult to put together. Just be sure you line up the springs and the holes correctly or you will end up back-tracking like we did. The kit comes with a tool to put the springs in the holes. Once we figured out the easier way to do this, it went quickly. The rest of the parts were all easily explained in the directions and simple to put together. One of the plastic clips has broken already (one near the entrance) but there are so many that missing this one isn't a big deal. My children are enjoying it immensely!
I bought a trampoline from Upper Bounce about a year ago, and after just a few months, the pole caps that hold the net in place started to disintegrate. Somehow the type of plastic they use for these caps does not seem to tolerate the sun. When I called the manufacturer, I was told that these caps only have a warranty of 3 (!!!) months, but they would be "generous" enough to sell me the caps for the wholesale price of $3 per piece. So please be aware of that and check those caps before the three months are up. Or better, buy a different trampoline with a higher quality enclosure that will let you have fun with it for more than one summer. In addition, I did not find this trampoline easy to set up at all. The poles that hold the net in place were really difficult to attach properly and they are also rather flimsy. This is definitely NOT a trampoline for wild kids that like to fall into the net as much as what other trampolines allow you to do.
