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!

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.

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

The ratchet broke, sending my daughter tumbling to the ground.
Update: well we’ve had it nearly a year now, and my daughter was swinging on it with the included swing that came with it, and suddenly the ratchet came apart with a loud pop, and she fell to the ground. She’s only 10 years old, it’s not like a big adult person was on the line. The ratchet is just not made well, and I guess it’s just a piece of junk. So I wanted to give everybody this update. Now, I can’t really recommend purchasing this item because we put it back together after it had snapped apart, and a few seconds later with nobody even touching the line, it blew apart again. Definitely a safety hazard. When the package arrived, I was surprised that the box was smaller than I imagined, but no - it's all in that one box. Before we started any assembly, we did lay everything out in an organized fashion to make sure that everything was there - however, there was no inventory sheet that gave quantities. So, after contemplating for the 100th time as to where to put this thing, I decided on a tree and a gigantic 6" gate post. Mistake #1 - a 6" diameter post is not strong enough to attach to. Although our post had 48" in the ground, and a full 8-feet above ground, after we installed everything, I was worried that the top of the post was going to break off, because it was leaning over due to the strap on it. So we took everything down, and back apart, and started over to a new location between two large trees. Mistake #2 - Once you tighten the strap, you cannot move the buckles to adjust the placement of your obstacles. And, you don't want to be tightening/loosening the top strap too many times, because 1. You're probably on a ladder, and 2. It takes an immense amount of tension to tighten the strap. Things to note: 1. The straps have to be SUPER TIGHT to allow the kids to stand on or hang from them without a lot of sagging. Tightening them is not for the faint of heart. 2. The top strap has to be pretty high, or the kids just pull it down too far, even with it super tight. 3. The bottom strap - we decided to move it between two other trees, and purchase a third strap to use for it's top strap, so that they could use the strap and balance-walk on the bottom one. Because trying to have a bottom strap under the obstacle course was just a pain in the butt and not worth it. Especially with the swings there. My daughter likes to swing on the swing, but the bottom strap was in the way. So moving it was the right answer. Also, keep in mind that you cannot get to the other side of the bottom strap with a lawn-mower. So our new location for it was next to our garden shed, where I have to use the string-trimmer anyhow. 4. You need BIG TREES to attach this to. I would say that at least 12" diameter trees would be the best. I cannot stress enough how tight the straps must be to support all of the weight of the obstacles, plus the kids. Overall Opinion: I bought this to get my daughter outside and away from sitting in front of the TV all day during the summer. She loves it, and has already spent a lot of time on it. We also paired this with an outdoor gymnastics mat (inflatable, 20-feet long) and between the two, she is burning a lot of energy outside in the fresh air! Another thought is that, instead of the fabric strapping between the trees, what may have been a better option, and may still be for us, would be to just use wire cable and a cable-winch or come-along to tension the wire. Everyone has their opinions, but we also have a 90-foot zip-line, so we have a little experience with trying to keep a long line tensioned! Cheers!

⭐️⭐️⭐️⭐️⭐️ 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.
