Zipline Kit for Kids & Adults – 52ft Backyard Zip Line Set

The zip line hardware is of excellent quality, thick and sturdy steel. The trolley itself is heavy and solid with nice, high quality seeming rubber grips, and the trolley doesn't flip over even if there is no seat attached.The customer service is as good as promised - I sent them an email and they emailed me back by the next morning.It was "relatively" easy to put up. The assembly is straight forward enough. The hard part is getting the slack out of the cable, which weighs a ton. I did it by myself once, but it was quite a bit of work, loosening one U-bolt, pulling as much cable as I could, re-tightening the U-bolt, maneuvering a ladder around under the middle of the cable to lift it up, etc., to get it as tight as possible by hand, and then tightening down the top turn-buckle nearly all the way.The second time I did it (we moved from one set of trees to another), I borrowed a ratcheting tool specifically designed to pull up the slack from a friend who also has a zip line. That made it MUCH easier, although its an expensive tool that you basically are going to use once or twice. So I would recommend just trying without the ratcheting tool, but probably two people to get it as tight as possible.Ours came with a heavy plastic block attached to a thick bungee cord as the brake system. The plastic block has a hole in it through which to thread the zip line and then it slides until the bungee reaches its limit. It seemed pretty solid and worked well, but after about 8 months, the zip line started cutting the hole in the block wider. I contacted customer service, and they emailed back right away and said they'd switched to a steel spring brake system and would send me one right away. Sure enough a few days later it showed up, no fuss.The zip line is a lot of fun. It was a hit at our daughter's last birthday party and inspired some friends to get one (the friends who have the ratcheting tool). And its pretty good exercise probably - like with sledding, once the kid has ridden down, they have to run back up the hill with the trolley in tow.Grown-ups have been known to take a turn now and then as well.I highly recommend this product.

All my grandkids love this zip line, I'm so glad I purchased it.

Easy set-up and take-down. My grandkids loved it, but it definitely required adult supervision: we put a stepladder at the start of the run, and I had to catch them at the end of the run to keep them from banging into the tree that the strap was attached to. Did not work for adults, because there was too much flex in the strap, even when very tight.

A trip to the hardware store was needed for one fastener. The bolt that goes through the Trolly and holds the Trolly Locker in place was missing. Other than that issue the installation was simple, instructions were clear, and everything provided seems to be excellent quality. This would have been a 5 star rating if all parts were included.

Kit arrived missing multiple parts. Contacted the email address listed on the instructions. They sent an entire new kit, which arrived in 2 days. Was able to complete installation in a few hours. The ratchet strap was extremely useful for getting enough tension on the line. Now my kids can't stop riding it!
