Great for indoors
I grabbed this for our basement because cabin fever is real. 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.

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!

A Backyard Ninja Dream Come True
We bought this ninja warrior obstacle course for our 7 year old daughter and it has been an absolute hit. 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.

Good buy and quality was good!
The boys were excited to get this and the installation wasn’t too difficult. We used two trees. However. They lost interest pretty quick and hopefully the Spring will spark the fun again. Very nice quality!

Fun for the kids
The kids have loved it. And it is absolutely great for them. A few things that would be good to know: - I bought this one over the other because the weight limit was 600lbs. That would give me the ability to play on it with the kids when they ask. I don't quite trust my weight on it (a little less than 200). I can get on it but I don't feel like it would withstand my weight on it for too long. Since this was a gift for my twin 5 year olds it was not a deal breaker but I won't be getting on it. - You can put this up with only one person. It's a little difficult to do on your own so if you can put it up with two people I would do that instead. - Pull as much of the slackline through the ratchet before cranking it. The ratchet can't hold a ton of the line so pull as tight as you can by hand before cranking it. - the felt tree protectors didn't wrap around my tree. The slacklines did but the felt isn't the max length so if that's important to you than you might need to buy more of that. - After an hour of putting this up I realized a piece was broken. I really did not want to have to take it down to re-box it and send it back to amazon to replace so I contacted the seller directly. They responded in about two days but then went above and beyond to replace the thing that had broken.

durable and entertaining
My niece loves it! A bit of a struggle to put up, but that is entirely reasonable. Definitely takes two!

⭐️⭐️⭐️⭐️⭐️ Fantastic outdoor activity for active kids – still great after 2 years We bought this Ninja Warrior obstacle course for our kids and it has been one of the best outdoor play purchases we’ve made. The quality of the line and obstacles is really impressive – everything feels sturdy and well made, and once it’s set up between two trees it feels secure and safe. The kids absolutely love it. They spend ages outside challenging each other to get across the course and trying to beat their previous times. It’s been great for building strength, coordination and confidence and keeps them active in a really fun way. Setup was fairly straightforward and the instructions were clear. It does take a little bit of adjusting the first time to get the tension right, but once it’s up it works really well. We also like that you can move the obstacles around to make the course easier or harder. Pros • Very sturdy and good quality materials • Keeps kids active and off screens • Adjustable obstacles to change the difficulty • Great fun for multiple kids Cons • Needs two strong trees the right distance apart • Takes a little time to set up initially Update after 2 years: We live in Australia and this obstacle course has held up incredibly well outdoors. After two years of regular use it’s still in excellent condition and the line and obstacles are holding up really well. Overall we’re extremely happy with this purchase and the kids still use it regularly. If you have active children who enjoy climbing or obstacle courses, I would definitely recommend it.

OMG the quality of this set is amazing. All heavy duty materials. Heavy duty buckles and straps. Delivery time from order was two days earlier than originally indicated. I'm extremely impressed by this product and the service. Amazing quality product.

Kids loved this set, however be aware that the triangle rings WILL come defective. I reached out to the company and they responded immediately with an explanation and offer to replace, but then they never followed thru with the actual replacement, crickets from the company after that first email. Pretty annoying that all 3 hanging triangles had to be tossed out, straight out of the box. Still hoping they reach out eventually to follow thru with replacement.

Grandkids loved this. Used maybe 10 times and the ratchet became faulty within 12months. Unfortunately I went back to the seller after the warranty period. Disappointing considering it was not used that much.
