I agree with everyone above about the MVP2 (with the aspire nautalis mini) is pure magic i made it 8 weeks on that thing before i got the need to upgrade and experiment. Which is more than i can say about ALL of the stick batteries i tried before. I prefered the one that came with the 16b clearomizer vs. the iClear 30. I had a bad experince with penut butter flavour in the iClear 30 ... tasted like i smoke plastic, scared me for life. I got a family member off cigarettes for 3 months with the same setup( still going strong ). Good battery life, good form factor, great quality, very reliable, some surface area to put stickers..(which is always a plus for me) cant say a bad thing about it. The only problem i had was the device stepping down in voltage when the battery got low which is very common, and some people (not me) say the button is too hard to push down lol.
