hi x welcome to the planet x
vamo is a good device for starting it means you bypass the ego battery stage, when you set it all up and are ready to vape if you put it on tho volt mode and then slowly up the volts untill you find a point that is giving you good vapour, flavour etc too hight and it will taste burnt yukky lol
as for juice well , every one has different tastes , if you are thinking about a tabacco flavour i have to say i have never found 1 that actually tastes like a ciggy . but have a good read around the forum and look at reviews x
when you see something that you miight like then feel free to ask questions x
