Hi all, I'm looking to buy a portable, i.e., battery-driven, vape. The stealthier the better; a pen vape is optimal because I could use it openly and everyone would assume it's some e-cig thingy. Price doesn't matter. I care a lot about air path, i.e., all glass is best, metal ok, plastic not really. I'd use it for herb only, but if it can do concentrates, why not. I think a pnp with the new glass tip would suit me, but I didnt find it easy to browse the whole thread on it to look for potential problems. Any help, hints, etc are really appreciated. Thanks!
