Earlier in the new members forum I asked about the new ego 3-6 volt vv's being sold by several different vendors. I would say at least 4 types are out there from Apollo dogs to Hoosier cigs kango model. Well, long story short I decided on the kango mega vv from Hoosier. I received it and my new vivi nova system today and am thoroughly satisfied. I put the vivi on my joyetech twist at what I assume was the same voltage(kango has LCD screen, .1 increments) and the twist just did not taste as good. On a side note, the vivi nova also beats the smoktek duct hands down imo. So, the ego 3-6 volt vv's on the market, at least Hoosiers kango, are winners in my book. Anyone else tried any or are thinking about it?
