Yeah, the wicking is no big deal, I could use another. I never have any leaking on fill up as I've heard of some having, as long as the o-rings are good.
The wicking was a bear for me.
Took a year of leaks and other symptoms to realize the Erlk likes/needs the wick to be tight in the coil. Guess I ain't as smart as I look.
I hurt my thumb a week ago and my weekly disassembly and cleaning of my Kayfun V4's was almost completely impossible to do due to essentially being left with one good hand to do all the unscrewing and what not. And brother, there is a lot of unscrewing to do with the V4's.
My Erlks on the other hand, (no pun intended) were a walk in the park, comparatively speaking. Made me look into ordering four more Erlks and retiring the V4's altogether.
The Erlks are also so much easier to work with and way lighter.
I have not even a hint of a leak with the Erlks now that I have the wicking down to perfection.
I even leave them in my pocket while sitting at work. This puts them in a horizontal position for hours at time but still no leaks.
