Review on Effective Combat Tourniquets: Pack Of 3 For Military Tactical First Aid by Paul Hubbard

These are copies of the North American Rescue Combat Application Tourniquet, or CAT. These are a poor imitation, and might fail on you - on foreign-made copies, the windlass often breaks easily.Do not trust foreign made copies of the CAT, and don't buy life saving medical equipment on Revain. Buy directly from North American Rescue instead.
