I have been using these at work and at home for about three weeks now and they are as good as new and have retained their strength as well. Only time will tell.
The website and the blister card packaging cites a few other uses such as securing yoga mats and sleeping bags, good idea!
Sure, ParaCord and just any old cord can do these jobs as well. They really work as intended for trash cans but putting two to six of these in your pack, using them along with contractor size/toughness bag liners, you could make a shelter incredibly weather-resistant.
Sure, there are about 873,534 ways to make a lean-to shelter or some variation of the wickiup.
This could be just another tool in your survival kit. If nothing else, your trashcans in your home will thank you.
