Review: High quality and tension - High quality
Review: Better Than Bungie Cords - I used these springs to replace bungy cords holding tarps on both ends of my pole batn. Every few weeks I had to change bungy cords as they would sun rot and break from over use. I use these springs now in place of the bungy cords and have't the need to change them anymore unless they rust, which should take a great length of time.
