Setup: Instructions were relatively straight forward. However, I found the QR code which linked to the video much more helpful. After I had the video, it took about 20-30 minutes to set up.
Ease of use: It was easy to get this tensioned and could easily support several kids. The main line between that spans between two trees was sturdy, and the use of the ratchet was simple and easy to release the tension for quick take down.
The reason for the three start review though is a concern for longevity. After just a week of playing, the stitching on one of the swings had already come undone. I'm gonna have to go through and inspect the stitching on all components for safety now.
