So I'm using the Vamo V2 VV/VW mod and it has a function that checks the Ohm reading of whatever you have on it. I am using 3.0 ohm (Boge I think is what it's called) cartomizers with my device and when I first put a new carto on my device the reading displays at 2.8 and after about 4 or 5 days it reads out at 3.3 ohms. I don't know why it does this but I had one carto that read out at 9.9 ohms and tasted absolutely burnt. Does the higher ohm reading mean that the carto is getting closer to needing replacement?
