2×56ft Ninja Warrior Obstacle Course for Kids - 600 lbs Weight Capacity, Slackline Obstacle Course with 8 Ninja Accessories - Monkey Bar, Rope Ladder, Gymnastic Ring, Arm Trainer and Monkey Fist

We purchased this set as a birthday gift for our twin 8 year olds. They’re gymnasts who are currently obsessed with American Ninja Warrior. They LOVE it. They ended up removing the bottom strap, but played on it every day until they could cross it easily. This has very quickly become one of their favorite outdoor toys. (We have many!)I heard a lot of gripes about the assembly process, but don’t quite understand why. With basic reasoning, my husband and the 8 year olds were able to set this up between two established trees in under an hour. The most time consuming part of the process was sliding the metal brackets down the top strap, then adjusting them when the strap was tightened and in place. Still, it was not a difficult assembly…Well after the return window had closed, a crazy storm front sent a small tornado through our neighborhood. It sent large tree limbs through our play set and Ninja Gym, snapping the top strap. (This was not caused by any kind of manufacturing defect…) My kids were so disappointed. I knew the company was under no obligation to help us, but reached out to them anyway. Within two days, we had a brand new top strap on our front porch at no cost to us. Their customer service was kind, helpful, and fast even well beyond the return window. We’re so thankful and would definitely do business with this seller again.

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!

The media could not be loaded. We bought this to add some fun to our woods . I was a little concerned the straps would get slack in them from the kids bouncing on them but they are very sturdy and we haven’t had to adjust them since we (my husband) installed it. You may need two people to initially get the straps the height you want but if you had to you could do it with one person (handy person). After that just add the swings and bars and rearrange as you like! My kids need the bottom strap to reach the bars but if you have bigger kids you could probably go without the bottom strap. I can already tell this is helping build their muscles and coordination. (My kids are 4.5 and recently 3 here in this video).

A little tricky with some trees and needs better instructions. Also, space out where you want to hang stuff before tightening the straps.

My daughter loves it.

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.
