Backyard Ninja Course for Kids - 56' Slackline to Fit Most Trees - Monkey Bar Gymnastic Obstacle - 8 Warrior Attachments - 3 in 1 Deal - Bonus Handle, Ratchet Cover + American Portable Bag Included

I really like this obstacle course! I got this for my 7 year old and so far it’s been really great. It’s very durable too because I even tried hanging on it with my weight (155 lbs.) and it felt secure. Shipping was fast and customer service was great- I had a question about the product and they got back to me within hours. The seller was friendly and responsive. **PRO TIP: make sure you add the attachments before hanging the line, the adjustments are so much easier with this hack**

This is actually our second time buying a “ninja course line”. I bought a kit from another brand on amazon but unfortunately, the ratchet side of the slackline wasn't long enough to fit around our tree! I had to return it. I decided to try out and purchase ActiveHero’s line and sure enough it fit perfectly with enough slack remaining too. My kids have so much fun with this product, very high quality! I have a 5, 9, and 10 year old and this course is awesome to keep them active instead of just being on their tablets all day. Also, the packaging was super cute and very professional. The directions it came was straightforward too. I was happy about it.

Bought this for my 8 year old son’s birthday party and it was a huge success! Planning a party is difficult, and honestly I was worried this product would be hard to assemble. After some trial and error, setting up took about 20 minutes. After setting it up once, i’m pretty sure I can do it next time in 10 minutes. I did message ActiveHero and they told me that they would record a video how to guide for setting it up! Really great idea I think that would help a lot. Other than that, the instructions are easy to follow anyways. The kids absolutely loved it! Will be using this for more kid parties

Great obstacle course for the kids, very durable material, and easy to assemble and de-assemble. Set up was a breeze. I’m only 5’4, so I did have to use a stepping stool to put the slackline higher up on the tree. This made the height perfect for my kid. I personally don’t position it too high just to make sure my kids don’t have a hard time getting on and off the handles. The entire course fits in the bag that it comes with so it’s easy to bring and transport. My kids love changing the hanging parts to challenge each other, such a great outdoor/backyard addition to our home. Would definitely recommend

WOW, literally hours of fun for the kids and less stress for us in setting it up! As a parent, this is a perfect play set to have especially if you’re an advocate for keeping kids off their phones and playing outside. We have my daughter’s friends’ parents asking about this slack line and have referred them over to ActiveHero here on amazon. Set up was only about 15-20 minutes. It was definitely a hit at our daughters bday party

solid and straightforward kit. Does everything listed in the description. Very good quality materials, especially the slackline. No complaints here!

We use it to set it up at our local park. Real easy and quality seemed to be strong too!!

We’re huge fans of the show American Ninja Warrior. That’s what inspired us to get this product! It’s the perfect starter kit for my son especially since he’s never done anything like this before (other than monkey bars). I bought this for my 7 year old and he loves it. I really like that you can adjust the course to the different heights. His cousin is a little shorter and the adaptability of the product is a plus. Would highly recommend this to others.
