Review on 50-Pack Black Ball Bungee Cords - Heavy Duty Elastic String for Quick Fastening of Canopy, Tarp, Ball Net, Straps, Tent, Poles, Wires, and More! by Jason Connolly

The tension is very strong and I learned how to hold the tarpaulin. I bought the same product 4 years ago and it has held up very well. None broke or fell apart. The original kit still holds my 12' x 16' tarp on a windy day. I'm replacing it now because there isn't enough tension to hold the tarp in place for it to spill water and not puddle. I got my money when I was 4 years old, so I bought it back.
