i did think of that!You might want to consider applying VG (or ejuice) to the orings before you put it together. Mine was tight but now can go from open to locked while on the mod - after a few tanks.
This thing does have issues but still provides a great vape. With the new single coil deck this might turn into a Narda with a tank, IMHO.
Its already been in use for more than a week and no sign of any improvement...
@Noodles11 There is plenty of AF just none of hit really hits the coil.
I will persist for a while and I'm sure I can get a decent vape out of it but the stiffness of the lock/unlock thing is really ticking me off...
