Ok well im starting to have issues now..... Just coiled a 0.36 SS coil, ohm checked on meter and then on evic mini and both read the same, locked in and was working great all day ar 410f 30.3w, I have been sat on a air-conditioned bus having a few stealth vapes and went to have one and nothing... Looked at unit and now have a 0.29 locked, let it cool do the whole remove atty replace atty reads correct lock again, have a vape, nothing, look at mod and its locked at 0.29 again.... Repeat process lock in 0.36 vape, bam worst f_ing taste ever. Not frigging happy I just inhaled that s@#t. I think something relating to drop in (I say this as going into a hotter enviroment, outside 37degree's is fine)ambient temperature changes is going on here here as the bus was way colder than my 23degree room i built it on. Yes I can coil, yes its only this device, yes there is something wrong.
