I have an Innokin Kroma Z and love it. Even got a few extra pods (comes with 0.8 and 0.3 ohm coils... like them both) Anyway... used the provided coils (0.8 defaults to 16 watts, 0.3 to 30 watts) Got some extra 5 packs of the 0.8 coils (authentic... I checked) First three coils (out of a 5 pack) worked fine (showed around 0.8 ohms and mod defaults to correct 16 watts. Coil number four read 1.01 ohms and mod went to 10 watts. I wondered if a 1.2 ohm coil got put in the pack by mistake. Removed it, wiped it off and it is a 0.8. It alsi didn't produce much vapor at 10 watts (no surprise) Didn't try increasing watts... just replace it with coil number five. Same thing... 1.01 ohms, 10 watts. What are the odds of two defective coils reading the exact same resistance??? I soaked number four coil in ethyl alcohol and let it dry. Just got a Zlide tank so going to put that coil in it and see what my other mods read for ohms. This doesn't make sense. Will update results soon (making sure the coil is totally dry)
