  • Great obstacle course. I would recommend it to anyone.
Size: 110 Foot Line
My granddaughter loves her double slackline obstacle course. It does take a while to install, and you will need at least one person to assist with the installation. The only thing that was a bit of a pain was stringing the carbuncles. as they had to be threaded down the entire length of the strap until you got where you wanted it. after getting these close we tightened up the strap to see if they would move. Since we had wrapped the one end around the far tree they did not move much. You will need to layout the obstacles so you can get everything close. After tightening the straps, you will not be able to move the carbuncles. We just looked at what we had after tightening and then loosened the strap enough to move the carbuncles where we needed them. I found that if you attach and obstacle to the carbuncle it helps when sliding them into position. After it was installed, I had a yard full of kids playing on it and it seemed to work very well. ... show more

  • Fun for the Kids
Size: 110 Foot Line
Overall, very happy with this line. It is very good quality. Keep in mind, you must have two solid trees to attach it to, it will require two people to hang and can take awhile to get set up but the company has a very helpful video. Just be sure to set aside the times. I have the 100ft one and there was a big chunk that didn’t have an activity (the ones it came with weren’t enough to cover the full line if you want the kids to be able to jump from one to the other) on it so would also suggest purchasing another piece like the net or two more activity bars if you want activities across the whole 50ft line (100ft in total but becomes 50ft when you wrap it around the tree). Would buy again. ... show more

  • Fun for kids, but keeping tension is a problem
Size: 110 Foot Line
The kids love it, but it loses tension easily and keeps slipping off one of the tree protectors. We've re-positioned and re-tensioned it three times, made a two kid limit on it, and it slipped again. The kids are between 7 and 11 and they don't weigh more than 125 lbs when two are on it. Also, be aware that there are only enough obstacles for less than 1/3 of the length of the 110 foot line. We have it strung across a span of 35 ft and still have dead space. ... show more

  • My granddaughter loves it
Size: 110 Foot Line
Got this for my precocious two-year-old granddaughter and she loves it. She has already mastered the wooden bridge. I like that it is expandable and the difficulty level can be increased as she grows.

  • Obstacles need better height adjustments
Size: 80 Foot Line
Purchases for our kids to exert more energy outside. Likes: kids think it’s great, and nice variety of obstacles. Dislikes: website stated it can hold 1000lbs (ie - many kids), though the instruction booklet in the box states a max weight of 250lbs. The ratchet strap also needed the excess cut off to allow for appropriate tightening between our trees. The Rickety ladder sits approx 3 feet off the ground at its lowest adjustment (too high for the littlest ninja measurement and exceeding the instruction booklets reco of no obstacle being more than 12” off the ground), while the rope swing then scrapes the ground. Overall, needs a few improvements to allow for adjusting the height of each obstacle but so far - mission met on happiness of the kids with it. ... show more

  • Fun!
Size: 110 Foot Line
It took two adults about 2 hours to properly set this up and get it ratcheted correctly. Once it’s up, it feels very secure!

  • Better than expected!
Size: 110 Foot Line
The media could not be loaded. We’ve been so pleasantly surprised at this system. It is versatile and has been so fun for our grandkids, ages 5-13! It took some adjustments with setup to make it high enough to be a challenge for the older kids. They really love it! It’s the first thing they run to do when they come over, and it’s an awesome alternative to the kids being in front of a screen. We really like the options available to customize. Recommend getting plenty of the d-rings to place on either side with initial setup, then you can add to as you wish. Also recommend planning some type of “ladder” option on the ends as a start and end point. ... show more

  • Wooden money bars molded after a couple of months
Size: 110 Foot Line
We installed the double slack line in the backyard in November 2022, it works very for a couple of months. Due to the rain in the last few days, we just found out all money bars are molded and I can’t find the contacts for the seller to request for the replacement online.
