... have one that I've been using daily for about 3 weeks (Top Vapor Root Beer 6mg) without cleaning and still going strong. Using an ePower 14650. CE2 R4 XL metal body.
It just died!
I put it on the multi-meter and its reading 402K ohms. What's up with that? I expected an open (infinite ohms). Is it possible it's just way too dirty and needs to be cleaned?
