Just some doubts i have

[elfstone]

Huh? There are CE4s, CE5s AND iClear 16s. innokin makes the iClear line and they have the iClear 16 and 30. I have never, ever seen the CE4 or 5 designation applied to an iClear clearo.

Meh... There are lots of much more interesting things to occupy one's memory with than CE* types, subtypes and brand names

If it quacks like a duck... That i-whatever looks like a CE4-type device, and Got Vapes refers to it as an "Innokin iClear16 Dual Coil Replaceable head CE4"
