I'm seeing on the boards that the ones that look like regular cigarettes are a waste of money? I saw my friend's last summer & she unscrewed the filter to charge it & I think the white part was disposable after it was empty. I didn't see her refilling anything. I've seen pictures of honking big things that don't even look like a cigarette. I haven't bought anything yet but wanted to know if the feel & look of a real one would help someone just starting out? Then maybe switch to something better? I have no clue what I'm doing, lol.
