I took out the atomizer, heard it click into place, put the cartridge in....NOTHING.
Are you screwing it in after you hear it click into place? I push mine in, turning slightly to the right, and once I hear it click I give it two or three good turns. I haven't had an issue with a single atomizer and I have them in matte finish, shiny, from several different places. However, I do prefer the Janty atomizer in it. If you've turned it after the click, you might just have a lemon. Unfortunately, it happens. Talk to Ethan.

. Just wondering if it's better for the battery to wait until it flashes that the battery needs charged or if I should just charge it when vapor starts to taper? I know these batteries are much cheaper than any others I use so it's not really that big of a deal, just wanted to hear some opinions on the matter. If this has been posted somewhere before please lead me to that thread. Thanks.
