We bought the 15' round trampoline in 2015 when our kids were 5 and 7 years old. The trampoline is really like an investment, the kids still use it! We have replaced the safety net, spring cover, and mat over the years, but I'm happy to pay for upkeep since the trampoline gets so much use and encourages exercise outdoors. Recently, one part of the frame broke. I contacted Zupapa, and because they guarantee the frame for 10 years, they sent me a free replacement part. Customer service was very helpful. I love that Zupapa stands behind their product. I would recommend purchasing a trampoline from Zupapa. It is a quality product.
