Atomizers are generally used only for dripping and can be a good way to test out new flavors without filling a fresh new carto.

Simply attach to a battery, drop a few drips of liquid onto the center and pop on a drip tip, you'll get a few good vapes without any taste from fill or other impediments. 

I also have one other similar type rebuildables coming, so stay tuned and bookmark this page :)

Please wash and inspect your purchase throughly, RBA's are machined items and can contain shavings or particles you need to remove.
