Its solid and trust worthy. Holds well on anchors but as the previous review stated, its a bit too stiff for most other uses. Over all I'm stoked, but will be using other cord for prusiks and slinging protection.
I bought this cord originally from REI for use as prusik cord for crevasse rescue. However when I opened it I immediately could tell that it was too stiff for use as a prusik and after testing it on my 10.5 rope it just slipped through. So I instead put a double fisherman's knot in it and converted it to a cordelette.
Like others have said, it is too stiff to be useful as a prusik. But, it is perfectly fine for making a cordelette. I prefer the Sterling or PMI 6mm for my prusik.
