I'm kind of disappointed, this new SS Vamo V3 is burning up my juice. I am constantly getting harsh burnt hits from the Vamo using a ProTank, or EVOD. Cartomizers are better but still doesn't taste as good as the eGo batteries I've been using. I've tried using Voltage Mode and Power Mode, LR coils, and SR coils. All I can think is it's this Pulse-width_modulation technology to simulate voltage, hitting the coils with 6.xx volts of power even through its switching on and off very quickly just causes the coils to heat up too much. And it doesn't matter if you set it to 5 watts or 10 watts it is still shooting the coil with 6~ volts every pulse.. I dunno I'm not an expert, I just know I'm not liking this.
