Best Toy Ever
Slackers Ninja Line is amazing! It is sturdy and stands up to all the stress we have put on it. It is easy to set up and the maintenance is quick and easy. There are so many options of things to hang on it, you can personalize it a lot. It got to the point where it was getting used around an hour every day. It is fun for doing stunts on, it will also get you very fit. It is an awesome, fun workout. Especially for your upper body.

Great for backyard!
I bought this for my sons 9th birthday. It it amazing! The balls are definitely a little more difficult to hang on to when compared to the wooden bar or the rings but it's nice that there is variety in the set. I also bought two 6 foot thing ropes from Home Depot and hung them as climbing ropes on either side of the apparatuses. Without the ropes my boys couldn't reach the rings or wooden bar so I was picking them up each time - the rope has really helped with making this something they can use 100% on their own. The NinjaLine is always a kid favorite for play dates and it's super easy to setup and take down. Highly recommend

Super fun for ninja warriors
This is a blast! My six year old loves it - we hung it between two posts next to his tree house and he uses it multiple times a day. Every kid who comes to our house immediately goes for the ninja line. It was fairly easy to install. The only thing we noticed is that there’s a lot of slack when my son actually uses it. We should have installed higher posts so it could have been higher. In the middle, his feet touch the ground.

Great concept!
Very cool product for the ninja warrior want to be. It is easy to set up, but you have to have 2 trees that are separated in distance by the length listed in instructions. It took us a while to find a combination of trees that would work. It is much harder for the kids than I thought it would be, but they love it!

Installed without trees
I'm pretty pleased with this setup, my son and the neighbor kids are getting a lot of use out of this. Since i didn't see any instructions online for installing this without trees, here is what I did. After some trial and error, I used 4x6 posts (30 feet apart) and installed them with posthole diggers as deep as I could, about 3.5 feet. I did not use concrete. The 6 in side faces the ninja line. I used 30 inch ground anchors on either side of the posts for lateral support (mcmastercarr part 6300A26) and connected them to the posts with eye bolts (3018T28) tensioners (2998T54) and steel cable. All the parts were rated for lifting at least 1200 pounds. I've had this installed for a few weeks with daily use and it is holding up. I check it everyday to see if the posts are still level, they flex when in use, but stay level below the lateral anchors.

Quality well done, details and instructions need to be revised-very poor.
Quality is great and our kids do thoroughly enjoy it. However, the instructions and details giving you an idea of how much space there needs to be to stretch it out and hang was very inconsistent and caused us problems in setting it up. We use telephone poles for the supports and because of it did not have the right spacing between ends. We had to add another strap for an extension.

Great quality
This is our second Slackers purchase. I am very impressed with the quality of their gear. This ninja line has 2 layers of webbing throughout the entire line that are sewn together with spaces left for the 'biners to slide through. The ratchet is strong enough to easily tension the line in a few seconds. We had it out of the box and up to use in 20 minutes. The most difficult part was getting the 'biners through the pockets. We found it much easier to do with a lot of slack in the line. There are 5 extra pockets to add more stuff. We added a rope ladder, the spinning wheel and a climbing rope.

Great product - harder than it looks.
It was easy to set up. I just had to attach each hanging apparatus to the slack line first. It fits nicely between the two trees that I have in the backyard. Now that we've installed playground wood chips underneath for safety, I will be putting it up higher so the adults can use it too. It is very hard...we are really working on our grip strength to be able to complete this. My 9 year old daughter has been able to get half way across. Now that it's starting to warm up, we'll be able to practice more and hope to report that we can complete it.

herausfordernd für 8-12jährige
Sehr stabil und eine Herausforderung für 8-12 Jährige. Macht nicht den Eindruck von Spielzeug sondern von professionellem Sportgerät. Hab sie allerdings für unter 100 € woanders gekauft ...

Super fun
Purchased this and a couple of additional obstacles for the course. Once you get the hang of setting it up it is quite quick to set up and take down. Kids love it. Seems to be of high quality. No fraying of ropes or cords of any sort. It even held the parents for a fun bit of time 😂
