I'd like to know too.
I want to help if I can though.
Up until now I use just a pair of small width hair trimmers as that is most portable. I have just bought a foil style Braun and its rubbish because it gets gummed up so quickly... Like after a single shave. I then have to ungum every single blade inside. The whole thing is ridiculous.
The clippers also get gummed up but less so and they appear to unstick themselves.
I can't carry and hate the waste of wetshaves. I'm thinking of open blade and peanut butter! Also maybe will try hair removal cream. Tempted to laser my whole head.
Yeah, I'm lazy in some sense but also in love efficiency.
