Quick clot works well. It is not for boo boos, however. As I was trained, it is designed to stop arterial bleeding where a tourniquet can't be applied. For best use it takes several people to apply: one to control bleeding initially (squeeze the cut artery), one to spread the wound to allow direct access to the artery, and one to dump the powder/stuff the gauze. Any of these people or additional persons need to be prepared to apply direct pressure for several minutes. If you plan to rely on this, or any emergency product, please get training in its proper use.
