Ninja Slackline 50ft for Kids with Monkey Bar & Ladder Kit - 9 Hanging Accessories Obstacle Course for Backyard | Warrior Climbing Training Gymnastics Set for Ages 5+ | Perfect for Outdoor Play, Backyard Ninja Courses & Kids Fitness Training

You need some distance between trees but we have 3 grandkids who play on it at the same time. I bought a disc swing to add to it. The clips make it easy to change accessoriesWe got this for our backyard but had to return because one of the trees we were looping it to looked very strained - almost as if it was going to be pulled out at the roots (and this was with our 10yo on it, under 90lbs). The tree is living and was just over the recommended diameter, so that was disappointing. It you have a number of very large trees to pick from (unfortunately we don't), it would likely be a nice course, but it was a no go for us.This came in much quicker than expected, so happy about that. My son is constantly asking to climb the trees and this is going to be great for him!Great fit for our backyard without taking up much space. My 5yr old loved it for his birthday! Took a bit if time to assemble and hang up (1hr total), but super sturdy and well built! As long as you have the support system to hang it, I'd say it's a great add.My 11 year old daughter researched and saved her money to buy this ninja course. We are so happy she chose this one, its easy to assemble and install and fun for the whole family!My three children love this! My husband strapped it to a tree in 5 minutes and they all started climbing. My children are 11,9, and 4 and all use it easily.Initial set up of installing all the hardware for the obstacles and spacing was tedious. Now that's over breakdown and install is simple and quick we take it camping with the kids love itjust thrown in box looks used NO INSTRUCTIONS PLEASE SEND
