I bought a Vision 3.5ml 2.8-3.0 Ohm Clearomizer from MadVapes to try out, and I am only getting burnt taste. I might get one draw off of it and the second is burnt. I first filled it last night and after having problems I decided to let it sit overnight so it surely would have time to wick. If I hold it upside down first I might get that one draw, but that is it. I am using a 60PG/40VG juice mix that has worked just fine on similar designs such as the CE2. I am using a VV device set really low, under 4V (unloaded), so low in fact that it is hard to believe that it is anywhere near 2.8 Ohm. If there is some trick to these let me know, I doubt I will ever buy another one but I would like to get my $8 out of this one.
