I usually carry para cord around, in the car, my daily rucksack, camera bag etc.
This stuff is very useful, 7m is a good length, the size is manageable, fits easily into a pocket & being bright orange makes it easy to find.
So far used it to secure wooden pallets on the roof rack & putting up a bivi in the forest for the kids.
Flexibility of use, length & the colour.
None so far.
