Americans like disposable stuff more than the rest of the world.
Double edged razors are big in Europe, where they still make them. In the U.S., it's a niche market.
We like disposable shopping bags, mp3 players, pens and lighters more than most of the rest of the world.
We can't get enough disposable e-cigs, atomizers and cartomizers.
It's a state of mind. Rebuildable atomizers will sell here, and they do.
But disposables have nothing to worry about.
If it wasn't for the Europeans, it might never have occurred to us that an atomizer could be rebuildable.
