Mini Vivi Nova

[Couture]

I have to start with I love my mini's. I got the full set with my first tank. 1.8, 2.4 & 2.8 oHms heads in there. I like the 2.4 oHms and can't stand the 1.8.
This morning I put the 2.8 on and after a couple of hours took my first draw from it. It blew the back of my head off! WOW why is the TH soooooo hard. I cranked up then turned down my volts and nothing helps. (eGo Twist).

Is this normal?

It might be primer fluid, they usually come with a small amount I think.
Maybe this one has more than usual, you could clean the head in Vodka and leave to
dry. Otherwise it could be a faulty head, a good 2.8 will definitely give less
TH than a 2.4 at same voltage.
