I ordered a couple of these for my wife and I ASP Key Defender and they just got here today. We opened them up and put them on our keys and headed out to dinner. Well, I realized the business end of mine was loose, so I tightened it back up. I didn't feel any liquid and couldn't really smell anything noticeable.
Well...a few minutes later I kept getting the urge to sneeze (after I rubbed my nose once). Not thinking much of it, we continued our dinner conversation and my eye began twitching. I rubbed it (no big deal, right??) and suddenly WHAM!!! I could barely open my eye! After going to the bathroom and washing my hands VERY thoroughly I grabbed a paper towel and began rinsing/washing my eye.
It probably wasn't more than half a drop of spray...but wow! That stuff hurts!
I'll certainly be more careful next time...
