Anybody familiar with Quikclot, made by Z-Medica? Supposed to be one of the best field treatments for major wounds, such as gunshot. I've seen a few scant mentions of it in regards to military personnel, as well as survivalists. I am interested in it to keep on hand in case I am first on scene of a gunshot/hunting accident, but primarily in case I'm shot. Just wondering if it works like they claim, and is it worth the price?
