It’s a good/great non- lethal product, if you’re not interested in deadly force and it will do the job.

I purchased the combo about 4 years ago, the Hero2020 and the Aiiro. They came in a nice case for storage which I use for extra cartiridges. Fortunately, I have never had to deploy either of them. I carry the Aiiro in my purse and the gun in my tote bag that is always with me. The other evening walking out of my office I heard some noise and reached in my tote bag for the gun. It had some white powder on it which I assumed was some wintergreen mints that were thrown in the same pocket. I got to my truck safely and put the gun away. I brushed the white stuff off my hands and absentmindely wiped my hands across my cheeks. They started to tingle. Not realizing what I had done I began driving. As I drove my cheeks got hotter and hotter which made me wipe them more. I began to realize what was going on. I washed my face with soap and water as soon as I got home and went to inspect my tote bag. The bottom of the pocket was filled with white powder and little pieces of red plastic. When I looked in the gun I realized one of the red balls had completely fallen apart. The other ball looked cracked. I took the gun outside to fire the second ball which was very uneventful. I then discovered that the cartridge had expired 07/24. Humm...I guess I should have paid attention to that. I cleaned up my bag and ordered a replacement clip. My takeaway from all of this? It works! A tiny bit of powder that was over a year expired still threw a punch!

Not a fun way to find out your cartridges need replaced! Sorry to hear of your experience. Our irritant cartridges have a shelf life of two years and should be replaced by the date on their sticker. If you have any question please feel free to reach out. And as always, stay safe out there!
