Kids Love it!
This is a great outdoor activity. Challenging enough for older kids (and even adults). Easy to set up between two sturdy trees. I would recommend for kids 8 and up as it can be frustrating for those younger than that. It’s been outside for a few months and seems to be holding up well.

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.

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!

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!

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

Nightmare
The product itself is high quality and the concept is awesome however, this has been nothing but a nightmare and I deeply regret buying it. DO NOT purchase if you don't have two very tall, large diameter trees that are at least 25ft or more apart. As seen in my photos, I had to install a 12ft post, which I buried 4ft deep and then cemented. I secured one end of the Slack line to the post at 8ft high and secured the other end to a palm tree also at 8ft high. It's approximately 25-30ft long. This failed miserably, so I then built a 8ft high pyramid in the center for support and finally, thought it was good to go. Nope. My 50lb 7yr old hung from one of the accessories and that 12ft post (which is buried 4ft and cemented) began to wiggle and bend. Additionally, his weight managed to draw the taught Slack line way down to the point he was standing on the ground with his knees bent and he's only 4ft tall. So now... I have to spend more money to brace the 12ft post and borrow a neighbor (a man) to see if he can possibly ratchet the Slack line tighter than I could. I'm a single mom, 110lbs and 5'4" and built this alone. The cost has been incredible because I purchased two sets of these obstacle courses... one for my older kids and one for my toddler and ended up having to purchase lumber, hardware and tools to accomplish what I've done so far and what I've done so far still has not been entirely successful. I'm super disappointed and feel like I should have either just bought or built a swing set or built an obstacle course using lumber rather than this Slack line system. This brand is great and again, the quality is great, but my struggle with this has been a nightmare.

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.

⭐️⭐️⭐️⭐️⭐️ 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.
