So my one mini Vivi ... cleaned it good Friday night and let it dry out, then gave it a vodka bath and let it dry out.  
*Then* I cut the wicks half their length.  Now that has made all the difference in the world.  My coffee juice actually vapes well now.  Gonna pick up a few more here soon.  Heh, now what to do with 5 T3s I bought on a CoOp, and 10 bases ... 
But yeah, the mini VN just looks better on an eGo battery ... I think it's the slimmer form factor.  The Kanger stuff is wider because of the eGo base.
