Was loving the titan...then had to change stem. Since there weren't any 2.5 I got the 2.0. Nothing but problems with it. Dry hits and burning hits. Am I doing something wrong..or is it maybe just a rare bad head. I am cleaning the other stem, so I can put it back in but wanted some input.
I'm having the same issues with the stock 2.5 and one of the spare 2.0s I got, on a freshly charged 3.7v bat (prolly around 4.2v). I've run 1.7 cartos on non-regulated devices for years without this issue. I've tried them on the Provari as well from 3.4 - 4.0v and nothing seems to help.
Gonna try a couple more of the spare heads I got this weekend...keeping my fingers crossed that it's just a couple bad heads.
I also tore a head apart - and I can confirm that they are NOT rebuildable as far as I can tell.
