So, until yesterday I've been using a vape pen. It was an Aspire ET with an Evode battery. The setup worked for me and kept me satisfied. I was using Aspire BVC 1.6 Ohm coils with 12mg juice. For some time now I've been reading and looking for something better. I picked up an I stick Pico with the Melo III sub Ohm tank. I dropped down to 4mg juice, because the 12mg was just...well you know. WOW, I AM BLOWN AWAY. The flavor and vapor is amazing. I am using .25 ohm coils and have slowly brought the unit up to 26 watts, and absolutely love this thing. The only question I have is where the he'll is all of my juice going. I think the next step is going to be DYI juice in milk jugs.
