I have a small canister of the Sabre Red pepper spray that expired in June of last year. So after a few beers, I figured what the hey. I wanted to see what the spray pattern was, and if it still did like the sprays in the past and infected the whole area. Yes it does. I live alone in a 1 bedroom apartment. So when I went to test it, I pulled back the shower curtain and just sprayed it on the shower wall. Huge Mistake. I've washed it down now. But I'm still coughing like a lunger and my eyes are watering like crazy. The gas chamber at Parris Island or several times during my service were nothing compared to that crap. Don't get me wrong though. Now I will relish the thought of spraying some miscreant that starts stuff with me. It's more effective than I thought it would be.
