Yeah. The wire box says on it UD Roll coils Youde Technology. The sticker on the back says '28 awg*2*Ribbon*5m Twisted Kanthal (3 wires).'
For my taste it's a little brittle of a wire which I don't like since the terminals clamp it down sometimes the grounding terminal snaps the 3 wire twist and then the whole vape misfires which I hate. Had to rebuild a few days ago with a 2-post atty in the simplest of 5 wraps with medium wick.
Now it works fine. Still in my opinion a bit of a mystery. Manufacturers website here for the wire. Likely wire in the coil I'm guessing.
Stuff seems brittle in my opinion in the future I will probably just roll a pure nickel non-twisted wire for ease and temperature control. This twisted wire snapped and caused one of my coils to non-ground itself between the grounding terminal and the coil. Fixed but hazard for sure if not noticed while dripping the juice. Overall though I'm actually using the same wire in a two post, two coil build on a aluminum atty which works fine. 5 wraps and good wick job (pat on back). Thing throws clouds pretty good on 50w with lots of airflow.
If they're UD prebuilt what sounds like tiger coils they're Kanthal A1. I personally dislike prebuilt coils...unless I know the builder. And the builder is almost always me. So I like my coils. Order some wire for yourself! Kanthal isn't compatible with TC...yet. Since you have a TC mod you should get some 28g Ni200 wire, and I'd say 24g Kanthal A1 since you think the UD wire feels brittle. The 28g Ni200 is brittle in a sense, it's just really really bendy and sensitive but easy to work with once you understand it.
Well, I decided to hold off on the pheno-L.. for now. I just want to see more reviews/feedback on it before I take the leap.. probably buy one later this month. Went to twisted messes site to order a couple decks and saw he released a blacked out RDA w/ gold plated pos pin. I'll let you know what I think in a couple days.
I just checked out twisted messes website and that black atty is effing dope. I may have to get it lol.
