I have a part time very minimal far sprayed in the bedroom from the bed and we could not sleep 1-2 hours anyway. It is therefore essential as it is also, never spraying in enclosed areas, if it not have to. (Burglars and etc.) In addition, it's just, as just described, very sharp and effectively, I guess. So I do not want to get in the face the part. In wind of course you have to be out carefully, as you might otherwise get it himself in the face, rather than the attacker gets it in the face.
