A bit easier than the T3 since the eGo sleeves are not in the way. Also the wicks doesn't have to be cut as precisely as on the T3.
In the beginning he calls it Vapeonly BBC, and later Vapeonly Megaclear. I think it's the exact same BBC we are all talking about here.
I'd say "trickery" would be closer to the original meaning.
I'll recap the points in the video that might only open up to us Finns:
The first hit he got was badly burnt. He had vaped it earlier without problems, so he decides to rebuild the coil. The coil system itself has a close resemblance to a T3, with three flavor wicks. He builds with .2mm Kanthal wrapped 4 times around two 2mm silica wicks. At first he leaves the wicks longer, but due to the difficulty of getting it together, he cuts them shorter later on. He forgot the rubber seal so it leaks and he gets juice in his mouth, but after putting the seal back it works well. He closes up with a comment that factory coils rarely work (on any device), so rebuilding is (always) recommended.
The guy in the video makes DCC tanks called "kiuas" (= sauna stove) for sale through a local forum, so I believe he's had a moment or two with different devices.
Either the coil is too tight around the wick or the wick is too tight at the slots going to the tank.
