Yup, after all my research, aka driving myself crazy comparing the same numbers over and over again on every available mod, those nights of going to bed thinking about the sigelei Zmax and waking up thinking about the Smoktech Groove, I bought a Vamo. I picked up a charger and some 18350 and 18650 batts. I hope it'll ship today and get here next week, because after it comes in the mail, all this mental angush should go away, or at least lessen for a while ...
