Hi, so I decided recently to move from a Sub-ohm tank to an rda as I wanted more flavour and it seemed like a natural progression. I did a lot of research first and bought some pre built coils just to get me started and used to setting coils/wicking. I brought myself an ohms meter and all the kit I would need. Now after dry burning and making sure coils are glowing evenly and wicking, my mod is showing different ohms. Typically it jumps any from around .250 to .265 to .278 or even .290. What I would like to know is if this is something I should be worried about? Thanks in advance for any help
