NTR 450 lbs Zipline Kit for Backyard - Zip Line for Kids with Multi-Play Wooden Swing Seat, Detachable Trolley and Ziplines Brake, Stainless Steel Outdoor Zipline - Outdoor Playground Equipment

The kids LOVE this thing.I have the neighborhood kids lining up to ride it. I use it as a reward system. "Pull weeds and you can ride the zipline for 10 minutes" and it works great.Impressive quality of the trolley and cable.The tensioner makes me a little nervous bc it seems like lightweight aliminum but its held up great for literally thousands of runs.I drilled straigh through the tree to mount rather tha around it.Both for tree health and sturdiness.Use 2 ratchet straps to tension it and its very easy.Put the strap on and crank it till it stops. Then the other one and crannk that till it stops.Then the first one again.Just keep cycling them.Make sure the tensioner turnbuckle is opened all the way. And once you get tension with the dual ratchet method you can fine tune it.The harder you tension it the fasyer and smoother the ride will be.

Only problems: Seat is boat shaped; not enough turnbuckle take-up to make for easy installation. Grandkids love. Recommend purchase.

Two of the nuts on the cable locks stripped the threads as I was tightening them. I had to go buy other cable locks. This makes me feel uneasy about the quality of the other included parts.

The Zipline is great and my 6yr old son loves it along with his cousins that come to play. The only thing is make sure you have two people at least because one person isn't going to be able to do it. The hardest part is getting the slack out of the line.
