When it’s warm again, I’ll move it outside. Pros: this thing is great. It’s sturdy and our rig has held bigger adults (ish— it’s a little short being in the basement, but we can still hang on it). The attachments are fun, but without a doubt the hit has been the extra swing I added on. It’s perfect for my 5 year old to work on some basic hangs and strength. Another pro is that you can set it up anywhere. And it’s easy to set up. Super easy. Cons: the length of the strap for small places indoors is a pain to work with. It’s LONG. Well obvious, you say and I agree. But it felt really long to slide the clips down 50’ of strap and wrap it. Just be wary if you’re working with 10’ of space, as I was. For small spaces, another con for me was how long the ratchet end was, as it creates 6’ of unusable space. I just hooked the activity bearing strap and the ratchet end to the same post and wrapped the strap around the second post to make it work. It’s sturdy and works well, just make sure you get the excess strap out of the way. We use it daily. It was definitely a great buy. Review: Versatile and perfect for the littles! - Installation was relatively easy. Two large trees are a necessity. Initially I was concerned about the trees being too far apart but this option worked perfectly, I believe it can go up to 60 feet in length. I chose this specific one because the quality is good! It stays outside and needs to withstand the rain, sun, wind and sometimes snow. Love how versatile it is in being able to put it as high or low as necessary. We choose to not use the bottom line because my kids are little. You can easily adjust height of swings. My only complaint is that one of the ropes for the swing came frayed which is a bummer but having it already set up, I’d rather just order a replacement if needed down the road. Moral of the story, my kids love it. It was as a great purchase! ## Features - TRAIN FOR NINJA WARRIOR - Whether you're a kid or an adult, the 2×56 ft Ninja Slack Line is the perfect obstacle course for demanding fun and physical challenge.

Will this product work for me? What is the best hanging ninja product for kids?** A: Hi, it can be used. Our tree protection is 3.2 feet long. The length of the webbing is 56 feet. It doesn't matter if the product is long. It cannot be shorter than the actual size. That is to say, the size between trees is within 50 feet. There is no problem in using our products. Thank you for your questions and support for our products. Have a nice day **Q: Hi - the "belts" to go around our trees are not long enough. Is there an additional piece that we can purchase that will work?** A: Sorry, we don’t have extra tree protection straps for sale Thank you for your questions and support for our products. Have a nice day **Q: I have about 62 ft between two trees do i need to buy extra line - if yes send the link plz - ready to buy asap** A: Hi, Thank you very much for your support of our products. If you need customized length, you can contact our official email: service@tzhuari.com Have a nice day **Q: If I order one of the expansion packs, will it come with more of the "special buckles"?** A: Hi, Thank you very much for your support of our products. Each expansion pack has a corresponding number of triangle locks. The blue and green ninja kits also contain a corresponding number of square buckles in addition to the triangle lock. Have a nice day！ ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for indoors *by R***C on January 31, 2021* I grabbed this for our basement because cabin fever is real.

From the moment it was set up, she was swinging, climbing, and racing through it like she was on her own backyard ninja show. It keeps her active, challenged, and smiling! Great value for money! Setup was easier than expected and everything feels sturdy and secure. We love the size! I love that you can change up the obstacles to keep it exciting as kids grow or when friends come over. It functions perfectly. It makes our yard look adorable too. It has been amazing for burning off energy and building confidence, strength, and coordination in a fun and playful way. This has easily become one of her favorite outdoor activities and it has pulled her away from screens without a single complaint. If you have an active kid who loves to climb, swing, and test their limits, this is such a fun and worthwhile purchase. ## Frequently Bought Together - 2×56ft Ninja Warrior Obstacle Course for Kids - 600 lbs Weight Capacity, Slackline Obstacle Course with 8 Ninja Accessories - Monkey Bar, Rope Ladder, Gymnastic Ring, Arm Trainer and Monkey Fist - Carson BugView 5x Magnifier Quick-Release Bug Catching Tool, Stem Educational Toy for Kids and Adults (HU-10) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/149273024-ninja-warrior-obstacle-course-for-kids-2-56ft-slackline-kit](https://www.desertcart.pt/products/149273024-ninja-warrior-obstacle-course-for-kids-2-56ft-slackline-kit) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-24*
