The only really good way to use an atomizer is to direct drip, well, unless you are talking about rebuildable atomizers which are a whole other ballgame. Some of the
devices such as the Ego-T, Eroll, Ego-C have an atomizer designed to use a small mouthpiece "
tank" as well I haven't had any personal experience with any of those.
The advantage of atomizers are:
They don't hold a lot of liquid, so they are perfect for flavor sampling.
They give a clean taste (no polyfill, no wicking) (well ss mesh wick unless you get a bridgeless one).
The idea with dripping is that you drip a few (3-4) drops depending on the atomizer, vape it and then put in a few more drops.
They were originally meant to be used with a cartridge that contained polyfill or foam which held the
juice, but I don't know anyone that still uses them like that as it's a pretty poor vape.
