Brought one with me to Iceland to have generally, and other reasons that won't happen, and... it isn't really working. When they got cold and wet out in the Icelandic rain, the beads got loose, which is the opposite of what I'm used to, or tested out before.
Best guess is that the new paracord (the 1,000 ft roll, that one!) is slightly smaller, or otherwise behaves differently. Will test more when I get home, but anyone else who bought one is free to torture yours and report back any results.
Ugh, now got to email everyone and offer to make right, cancel or hold orders placed, etc. Awesome.
