This conversation actually helped me a lot, because now I realized that it's more about the noise for me anyway - I don't trust my aim enough to settle for only spraying them, regardless of whether its OC or menthol.Oh i get all that, i was just offering an alternative that wouldn't cost 40 euro is all.
Whatever suits the situation best, would be ideal of course. Shame you have to resort to having it.
Also, the act of spraying anything towards their eyesight is a deterrent as it is. If I was a robber, I wouldn't trust that it's harmless lol.
So I just bought the menthol one with alarm from a webstore
