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.

A Huge Hit with the Kids
My kids absolutely love this obstacle course. It was easy to set up between two trees, and they've spent hours climbing, swinging, and challenging each other. It's also become a big hit whenever we have friends or family over for a barbecue. The kids all end up taking turns on it, and it's been a great way to keep them outside and active instead of staring at screens. The slackline and accessories have held up well so far, and everything feels sturdy once it's set up correctly. If you have a couple of trees in your yard and kids with lots of energy, I'd definitely recommend it.

Good for small children
The kids really like playing with it, although the 600lbs capacity is a little exaggerated. It sags a lot when my teens play with it and their combined weight is not very close to 600lbs.

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.

Kids outdoor ninja gym
We have a grandson that is seven years old and he is ADHD and he is constantly saying he is bored so we bought this and we put it up for him and he is constantly playing on it. Well worth the money very sturdy very well-made.

Wins Best Toy in Neighborhood
Update (9/2/20): We still love this ninja line. It has been up all summer and continues to get daily use and is still in the best shape!! Don’t hesitate if you are on the fence about this!! My son who is 5, is really interested in ninja warrior. He loves this slackline. It comes with everything you need to get started. It is sturdy, and extremely easy to put up and take down!! We absolutely love it. You can buy more accessories to change it up. We got a swing for my 2 year old daughter and she loves to play on it at the same time. It’s the best toy we’ve ever purchased! Especially now that we can visit local parks. Don’t hesitate to buy this!

Fun, but questionable functinality
We bought this set for our 10-yr-old ninja warrior for his birthday. He has recently started taking classes at a local ninja warrior gym and we thought this would be a great option for him to expand his training at home. While he and his friends had a great time on it at the bday party, he has hardly touched it in the week since. First of all, I think it needs more obstacles, so we will look into buying an expansion pack of some sort (but for $100, we wish it had come with a few more in the set!). Secondly, all of the boys complained that the small metal rings hurt their hands if they tried to swing on them like they do at their ninja warrior class. Rings are my son’s favorite obstacle, so the fact the there are only 3 in the set and they aren’t very functional is a little disappointing. It is also a bit of a pain that you have to position the obstacles while the line is slack, then retighten. So it takes a lot of effort every time the kids want to change up the order of the obstacles. Overall, I think we are happy with the quality of the set and will just be looking for ways to add new obstacles and replace the rings with either plastic or wood that have a bit more diameter so they don’t hurt the kids’ hands.

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