Ninja Warrior Obstacle Course for Kids Backyard - 2×50ft Slackline Kit with 10 Most Complete Accessories for Boys & Girls, Swing, Rope Ladder, Gymnastic Ring, Climbing Net, Arm Trainer and Monkey Fist

I bought this over a year ago when it originally came with the cast aluminum slide on webbing hooks. I did not install the system until MARCH of 2025. Once installed two of the web hooks broke almost immediately so I reached out to the reseller. They were GREAT. They sent me the replacement web hooks which appear to be much more reliable/strong than the original DRIPEX design. What I like the most about this product is the reseller behind the product. They could have easily told me the item was out of warranty but they chose to take the high-road and send me replacement buckles (free of charge) to address a safety issue they had identified. I would gladly buy from this vendor again (which is not something I can say for many other Amazon resellers.

I purchased the Ninja Warrior Obstacle Course for Kids Backyard – 2×50ft Slackline Kit with 10 Accessories on May 7, 2025. After just one play session, two of the metal connecting buckles broke. I was very concerned about further breakage; however, I contacted the vendor and was surprised and impressed by their responsiveness and willingness to replace the buckles with a newer, more secure model. I received the new buckles, and communication along the way was smooth and cordial. I am very impressed by the courtesy and promptness shown by Dripex.

Fantastic. Heavy duty. Kids love it. Easy to set up. I cemented two poles into the ground to hang it up. The straps are crazy Long probably double what you see in the photo. The only issue I ran into is the swing hits the bottom strap so we may just remove the bottom strap if the kids want to use the swing The straps are basically super long ratchet straps. Everything appears to be well made and sturdy.

You need a long distance between trees to set this up. The trees need to be strong. We only attached the top strap, and it still works. The kids have a lot of fun with it.

We were interested in having a play structure in our yard for our children, but we didn't want to spend thousands of dollars nor install something permanent that would take up half the yard even after they'd outgrown it. This has been a great compromise.I like the flexibility this system provides to rearrange -- and even replace -- obstacles/play items. The first photo in the review is what it looked like when I first set it up brand new. (Our trees are not very far apart, so I wrapped a single slack line around 3 trees, making 2 sides of a triangle. It's not perfect, because the obstacles at one end can run into each other, but my kids make it work.) The second photo is how it's morphed over a year and a half of use. I've moved obstacles around based on what order works for the play my kids are doing at specific times. We took down the cargo net because it was too hard for our 2 and 4 year olds and repurposed the 4 buckles it was using with a baby swing and a disc swing. (We also added a hammock and climbing holds on the tree.) I've loved watching the kids figure this out and improve their skills, and it has held their interest for the 18 months we've owned it. My 5 year old can traverse the whole course without touching the ground now, so we'll probably have to put the cargo net back up soon. And I'm happy to have the flexibility to adapt it to their needs as they grow.The slack line and buckles have held up surprisingly well to 18 months of intense sun (and even an ice storm that knocked down tons of branches from all those trees). The wooden bars of the ladder and monkey bars still work, but they're definitely showing signs of weathering. I regret not treating them with a weather-proofer before leaving them outside for so long. And the squirrels have nibbled away all parts of the tree protectors that were peeking out from the slack line.My impression before purchasing this was that it would be relatively easy to install, and we might put it up and take it down sometimes. But it was not. It took me quite some time just to get all the buckles laced onto the slack line. Then it took me and my husband a couple hours to fully figure out getting the slack line at the right height and right tension. Definitely not a one person job as I was imagining it would be. We have not taken it down at all in the meantime, though we just recently did loosen the tension a bit to rearrange the exact spacing of the buckles. We were able to do it, but we didn't move anything more than a couple inches because they were very hard to move.Beyond installation, my only complaint is that they don't sell additional buckles. The slack line is so long it could easily accommodate several more obstacles (if you have the space between your trees), but they only send the exact number of buckles to support the obstacles that come with it. If you could get more buckles, this would be so much more extensible.

We have had this for about a week now. So far the kids have been on it everyday for hours. We have not had to adjust or fix anything since putting it up. Getting it up and ready was also fairly quick and easy.

What an amazing set. There are so many things for the kids to do. There are so many items, I had to put some on my existing swingset, and the others on the line. The quality is all very good and should stand up well to the abuse my kids will put them through.

All the pieces and materials are excellent quality—everything looked exactly as pictured. This is our first ninja course, so I don’t have others to compare it to, but we’ve been using it with kids ranging from 6 to 13 years old.One thing I’ve noticed: the bottom slackline is a bit of a mixed bag. It’s helpful for the younger kids to reach and steady themselves on the bars, but for the older ones, it tends to get in the way. More importantly, it could be a safety concern—if a child falls off a bar or ring, there’s a risk they could get tangled in the bottom line. We’ve decided to not use it for safety.The obstacle heights also vary in accessibility—some of the kids can easily reach the elements, while others, especially the younger ones, find certain parts too high.If you use the entire 50ft there is a lot of extra space on one side or the other.Only one child can use it at a time otherwise the movement can throw another child off balance or be bounced off.
