I have a love/hate relationship with my eGo One 2.5 ml tank. I was so upset one day I almost threw it out my car window. On any given day it works as good as any sub ohmer I've ever had and on the next day, you can't taste your juice (weird) or it has minor leaking issues (frustrating) or the tank doesn't sit flush to the base (also frustrating). Most of these issues were with the stock coils from the manu. but that changed when I received the CLR heads. It was like it became a new tank for about a 10 days until I had to rebuild it the first time. My .5 build read at 1.0 and I guessed my wicking was crap so it leaked. Build #2, too much cotton and got several dry hits. Build #3 is a .4 but was intended to be .5 to .6 with 26 ga kanthal and it works ok with the cotton bacon I use to wick. I use it mostly for stealth situations but something keeps telling me that it can be great if I do something I haven't tried yet. Does anyone else have gear that you would consider "part-time"?
