    • Versatile and perfect for the littles!
Color: Blue Line 13 Obstacles
Review Image by Sarah Sarah
Installation was relatively easy. Two large trees are a necessity. Initially I was concerned about the trees being too far apart but this option worked perfectly, I believe it can go up to 60 feet in length. I chose this specific one because the quality is good! It stays outside and needs to withstand the rain, sun, wind and sometimes snow. Love how versatile it is in being able to put it as high or low as necessary. We choose to not use the bottom line because my kids are little. You can easily adjust height of swings. My only complaint is that one of the ropes for the swing came frayed which is a bummer but having it already set up, I’d rather just order a replacement if needed down the road. Moral of the story, my kids love it. It was as a great purchase! ... show more

    • So far, so good - but there are things I wish I knew ahead of time!
Color: Blue Line 13 Obstacles
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! ... show more

    • Seems very sturdy and is fun, poor instructions
Color: Blue Line 8 Obstacles(wood)
Seems like it will last for a very long time, even outside. However, instructions are lacking and they could use either instructional videos or better representations of the actual pieces for installation. While robust, some of the pieces are unnecessarily complicated. Still seems like a solid product though. ... show more

    • Great for indoors
Color: Blue Line 8 Obstacles(wood)
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. ... show more

    • Our second ninja course!
Color: Blue Line
We had a similar ninja course for our grandchildren to enjoy when they visited, but it was accidentally broken by a landscaping contractor. I had difficulty finding a replacement line of the same width so we could reuse the various hanging items. So I ended up purchasing this course which was not difficult to install. You just need to plan where you want each item and the distance apart to place the hanging carbiners (depends on how far the child(ren) can reach as well as how proficient they are at swinging to the next item). We still need to install the bottom strap which I think will help the younger grands - our previous course did not have the second 'tightrope' style strap. ... show more
