OK, here's contrary opinion. If it's windy, then (a) it blows the repellent away, and (b) more importantly, it's not needed anyway. If it's CALM, or nearly calm (<5 mph), then the repellent hovers around me, I breathe it in, and it gives me a headache.
So, it only works for me when there's just a slight breeze, around 5-10 mph. Just enough to keep the heavy fumes from gathering around my head, but not so much as to make it completely unneeded (when the pests would be blown away anyway).
