That's quite a unique sounding way to fill it!
"The unique new filling system of the ö Erlk ningin is made so that you don't have to loose screws or open. Even the driptip. Tighten the closure a quarter turn, and a fill hole is visible. During the filling disappears the unneeded air from the tank through another hole. Now turn the closure 45 degree back, and vapor continue. All without leaks and mess!"
Does that work as advertised?
That does look awesome! Too bad they don't ship to the USA!
Beautifully wrapped coil
