I had to use the Mean Green as security service often. Many sprays the effect too lax or not even present. The Mean Green tops everything I had to use previously by far. Immediate onset of action, reminiscent of a horse's kick: incapacitate, temporary blindness and severe shortness of breath. Panic at the attacker has the advantage that you can quickly get out of the situation without having to be physically active. Spray advantage: no contamination of uninvolved people as directly targetable. Even four-legged friends give whining heels ... hence the security products at all !!!
