Looks like a great atty. 2 comments - it's cheaper on fasttech and how come there's no airhole beneath the coil or anywhere on the deck that I can see?
The FeV is amazing...
When looking for a clone I was pointed to the Hotcig version as being the best version out there. That is why I gave the link to FC since I don't know the MFG of the FT version. The DT on the clones needs to be changed, and the base rings are a little wobbly at the start but settle down after a bit of use. Of course non of these are an issue with the authentic, but I don't have €115 to spend before shipping and I think they only ship via DHL. It would be just over $200 CAD to have one landed here.
The air hole is on the base section and lines up with the coil center. Just think of a dripper with dual posts and a single air hole on the side.
Coils are built dead center or off to the side and your wick lays on top of the screws. juice is provided to your main wick using a pair of feeder wicks (which are tiny mesh straws that you only need to make once), in the holes of the tank base unit.

Just pull your wick through and chop off the tails just a bit past the screws. Easy Peasy!
You can control the juice flow with the two mesh straws by changing the size of the opening in the center of them.
