Soldato
Yeah the online reviews all say that the vapor flask will only work with VTC4/5 or LG HE2 batteries, but I have 4 vtc5's, but they came from uk e cig so cant be sure if they are real... but they have been working great in my sigelei 100.
And yes, the Flask is the new version 2.1 DNA 40
Slinxy, PBusardo did a review of the CF MOD, as I recall it is not regulated, it simply has some built in protection but is otherwise just a mech mod, so as the battery dies, so will your vap.
I thought the review was on the CF battery and other CF mod reviews said it was regulated.. never mind.. It does look pretty thou
UK e cig are doing refunds on The VTC5s that they sold according to UK vapers forum.
