I recently purchased these: https://www.madvapes.com/Refillable-510-Cartomizers_p_2481.html.
There's a little rubber stopper at the top for the mouthpiece. When I take this off, there's a little straw looking hole and then filler that surrounds this. When I fill this with E-juice, the juice just drips out the bottom where it screws into the battery, lol. Is this normal? Or, is it supposed to be already screwed onto the battery when I'm filling? It hits good atleast.
