The title is self explanatory I've been doing it for a really long time it got me to quit analogs but I still crave to just be able to hold it between my fingers.
Alternatively, one can purchase the Blu Starter Pack and refill the cartridges on that. They also have the 510 threading, if I'm not mistaken.
However, again the issue will be battery life.
Kanger eSmart Clearos on an 808d battery
Works out to the same diameter and just a tad bit longer than a 100's style analog. Problem is the 280mah batteries don't last that long so with a pair you are always charging. Drove me nuts.
