Pretty sure it's a V2 after catching up on the vamo sub forum. It's got the metal buttons, remembers wattage after a battery change, doesn't blow up coils on first fire after switching resistance, and has a positive post gasket. Those appear to be the hallmarks of a v2 (from what I've read thus far).
I also was VERY hesitant to import it on my own, but after this experience, I will be much less so.
Excercise some Google fu on how to avoid scammers on alibaba. Look for verified gold suppliers that accept escrow and you've got a good start. I didn't escrow my payment, as the escrow system seems build more around subsequent volume orders.
The unit arrived via DHL, signature required, after 4 days.
I ordered 4 efest imr 1830 seperately from a US website just to be sure I had a good supply of batteries. The 'special lithium batteries' that cam with the unit are flat top 900 mAh bits, but in the Vamo, they seem to work just as well as the efest IMR 800 mAh batts.
