I have for weeks been apply everything to my neck. I did use to put them on the back of my hands, but I usually wash my hands A LOT! …I am very hygienic! lol. Just wondering if it makes a huge difference in diffusion etc. Because I am 6ft tall. And obviously most girls are much shorter! lol.
Usually, neck, head (hair) and chest are most effective, since they have the highest SA with a lot of heat being given out. Hands and wrist could be effective if you put your arms and finger very close to your target.
Head and Neck are the way to go!
Also works well applied on legs if you wear shorts. The backs of the knee are good. I oft give a zap to the zipper area for good measure. Seems to attract them to that area quickly.
Cheerz guys!
Thanks for the tip 
Have you ever induced crotch staring or crotch lunge and grab with the zipper application? Now that I would do it I’m just curious to say the least.
