TIME TAKE OUT MY DCA306!
These are 2.5ohm 306 atomizers. They come with a drip tip.
These work on a standard 510 connection, and some drippers prefer them over a 510 because they hit a little harder. The drip tip goes over the atomizer protecting your mouth from the exposed mesh.
These work nicely in a DCA306 setup, I have used them in the past.
