Bought this for my daughter for Christmas. She uses it daily and it has held up great in the Arizona sunshine. The bottom supports are very sturdy, and the way they are bent keeps water from getting inside and rusting them out. Assembly was easy for 2 people. I removed 6 springs to give it some more bounce, as it is very stiff with all of springs installed. I figured it would loosen up after breaking in a bit, but after a year of use, it is the same. The enclosure is disappointing though. All of the bottom clips have sun rotted away from the netting, and the plastic post caps all got brittle and the posts popped through them, leaving the netting sagging down a bit and the tops of the posts exposed. I am ordering another one since it has saved some accidents and is worth having installed, but it would be nice if it was the same high quality as the trampoline, especially for the price for what looks like the need to replace it every year. If the enclosure was better, I'd give it another star.
