Yeah, he is crazy. Even more so if you understand the German: "So, if you don't know what to do with these extra parts, you can easily built an A2-like atomizer". Yeah, right.
But I like him very much, a very helpful guy, invented a few ways to wick-and-wire the Ody, too.
Oh, and the wick he uses is "Ortmann" - a brand that's often used by German vapers. It's a bit fiddly and doesn't take well to heat and dryburning.
If you need parts translated, just ask, I'll do my best.
