Honestly I couldn't get the flavor I wanted but I'm fairly certain it was me and probably my wicking. I didn't give it much time either.
I sold it to a guy who sold me his Hurricane. He loved the UT and I loved the Hurricane. Just shows there are so many variables.
I have considered getting another UT and giving it another go but with the really nice RTAs coming out with top fill (KFV3 mini, Kayfun V5 and Calix) I'm not sure I'm going to invest in any more bottom fill tanks.
I finally got the Gem built where I really liked it and then it started jumping ohms on me

This is a known issue with the clone for sure and I'm hopeful I can get it fixed but it is a device that takes a LOT of fiddling. But dang, it is such a sweet looking tank and gives really good flavor when built right.
