I used these mini bungee cords as tensioners for 4 clotheslines on my pop-up camper, underneath the bunk ends (the tent-covered ends that stick out, for anyone who isn't familiar with them). I added them 4 or 5 years ago, and I'm still using the original ones, except one which broke when it caught on something inside the camper while deploying the bunk end. The only extra tension they get is when we hang up wet towels and bathing suits. Note, they are out of the sun 100% of the time, being under the bunk ends. That probably helps prolong their lifespan.
