I re-checked out Mx297
I still hate the scent of it but I can bear with it at 1 spray only 
To the neck every time, I’d love to spray on my arms but oh well it’s Winter…
I tested 1 spray over a few days.
The duration is roughly 3 hours and the range medium (~3-4 feet maybe indoors, 1-2 feet outdoors)
I got some subtle hits from class mates, those who are around me use the opportunity to start a talk and I’m usually a bit giddy wearing Mx297, knowing I’m in the spotlight. They react positively to it.
No hits from girls I noticed (outdoor -> tram -> class -> tram -> outdoor), but it was only testing for 3 days so no conclusions here, except one who seemed to be totally confused and not being able to think clearly while being around me.
Atm I see an effect but am not really satisfied with it. Will keep you updated!
