I just bought a Metal Dual 510 Cartomizer Tankfrom Altsmoke (AltSmoke.com | Metal Dual 510 Cartomizer Tank - Color - Tanks - Cart/Rebuildable - Accessories | Electronic Cigarette | Ecigs |.) After I filled and primed it, I screwed it onto my battery and noticed it was hard to screw on as it kept turning. Then I saw that there was play in the cartomizer - it sticks out about 1/8" on the top of the tank, and the tank itself slides up and down (see photos.) So the tank slides up and stops when it hits the larger part of the drip tip.

Is this normal, or am I doing something wrong? I never have screwing on issues with my Vivi tanks, so just wondering what to do here. Thanks.
