Question: where can you buy the brake
Document: Easy to set up. Boys love it. Like the light up seat at night. Would recommend the brake system that doesn't come with it.
Everything works well. We had a birthday party at our house and it was a huge hit.We had a have incline. Make or buy a Zipline break (basically a block of wood with a bungee cord in it) to stop the Zipline before the end. There are some for sale here on Amazon, or on the internet to build.
I used one tree and built a platform five feet above ground (later attached a slide and a rock climbing wall as well. ) Zip was secured six feet above platform. It works well and was easy to install with two men. It took about two hours to get it right but is maintenance free. May buy another one.
Yes, you need a few good trees. Yes, you should either get a brake stop or only use a slight decline. This thing will fly downwards if its to drastic. I would use a cable puller if older kids or parents plan on getting on as it will sag if not tight enough. We used a few heavy duty pool noodles at the end to stop the kids and pushed the trampoline under so they could just jump off. Works great.
This thing is 100 feet long. I set it up by myself in under an hour. If I had someone helping me it would've been set up faster and my kids wouldn't hear my curse words. My friends weigh about 200 pounds and they used it and I felt like they were probably to big for it but still safe enough not to brake it. It looks really cool at night because the seat and stuff lights up. This is the best 100 bucks I've spent in years.
preformed better than expected ; great family fun.very low maintaince .easy to install.would defiantly recommend for all families.
We purchased this item for our son and it was missing parts. Make sure you check the box before spending all that time outside installing, so you don't have to take it all down and reinstall.
This was easy to install, but poor quality. The lights all broke and fell off and it's rusted out after five months.
Our boys and neighbors love this! It is do much fun.
Of course I love it too. The directions were well done and it was easy to install. Thinking on buying a second.
Answer: yes
