I tried a Kanger T2 recently, and after trying some of the "FIX" methods on it I still get too much burnt taste. I have the same issue with the 2.0ml Vivi Nova as well after trying the "FIX'S" for those. I see all the vids of people using them with great results and am quite puzzled. The 3.5ml Vivi Nova v3 is the one that works best of the 3 clearomizers mentioned. When they work well there is no comparison with regular cartomizers. Too bad they only work 25% of the time. I have to say, today 3/10/13 my Vivi Nova 2.0ml seems to be working decent. Unpredictable
