years. I bought a roll of SS bandit material as well as the end units years ago. It lasts forever because there aren't many reasons to us it on a boat but when you need it there isn't anything that could replace it. Mostly I've used it in place of hose clamps where I didn't want the screw arrangement of the clamp to be in the way or the long end that's left over to rip up my arm. It would be unmatched for repairing a broken mast, spinnaker pole or boom.
