Something like the Vamo can do everything this can do and much more.... The Vamo is a good backup.... I doubt you can vape out of this box in a pinch.... If you have more money than you know what to do with buy this... If you want a good electronic dedicated meter buy a multi meter.... It cost lest than this and can also test your batteries... Do what you will but something like this will never see my vape dollars.... BTW FT just listed a bunch of MM.
