Well I wrote a huge reply and it didn't take. Gonna summarize it this time. I just got an mvp2.0 with an aspire nautilus mini tank and iTaste vv v3 2 days ago and I'm in love with all 3. The iTaste battery life stinks but it makes up for that in portability.
What amazes me the most is how there are so many flavor profiles in the same bottle of juice found by using different volts, and different temperature with different watts. Right now I've been experimenting with moo juice and love seeing how different creams vs strawberry comes out with different volts.
On the deals and steals page there is a code for a $24 iTaste at 101vape, and they also have the best price on the mvp2.0, both scratch off show they are genuine innokin products when I checked on their website.
