I came across Rhino Rescue equipment couple years ago and decided to give them a try. I have used almost all types of tourniquets and can say without a doubt these are as good if not better than other higher priced ones. I recently hosted a class and showed them to compare and can say in my opinion they are better made the others and the band tightens up faster then any other. I have now changed all mine to these and at any given time I carry 20 in my vehicle at all times.
