As me late last year a wild dog weaknesses of this product were attacked aware. The Guardian Angel II has only two weft of which at least one must be seated, otherwise no effect. Especially for me as inexperienced shooter it was not possible to ward off the beast. My first shot I missed and shot straight in the forest floor, my second shot hit the animal only to back and side and thus unfolds no effect.
I think that a defensive spray is more effective especially in agile attackers, since one during the "penalty mark" still Nachzielen can to correct his shot.
