The atomizers for my e-cig cost way too much. $15-$20. I saw the ones for the 510 are only $7.99. Could I use it with the one I have? My e cig seems to be about the same size as every other traditional one. Also, could I use the charging pack from my e-cig with another battery, say the 510. I just find it very useful and don't want to give it up.
