Is shot selection critical?
charge in the grille. Connect with a flying mossie and it’ll expire instantly with a spark and a sharp crack.
For insects, certainly. For humans, a touch on the grille is uncomfortable but not hazardous. (Idiots’ disclaimer: don’t use it in the bath or in petrol stations.)
Is it dangerous?
Backhand, forehand, smash… they all work. Only go for airborne targets, though; you don’t use it like a swat.
It’s more efficient than a hand-clap, more agreeable than a chemical spray, and more fun than both. Anyone for death tennis?
