I saw a few vertical rebuilds and gave it a try with mixed results. Did one for my evod and pro mini 2 v2(.....!)the first two lasted about a load and a half (refills) and I haven't had one last that long since. Not sure if its not enough wick or to much, tighter coil, or wider coil, I just get leaks. I lost my place with the other post, can't remember the title/page (duh), so if you can tell me which one to read or give me advice I would be very happy. Thanks in advance, as always,
Joe
