Hello everyone, so i purchased an "authentic" protank from fast tech. Tested it on my mini lava tube man it was awesome for the first hour; So im adjusting the voltage trying to find the sweet spot and at 3.4 volts i get a burnt taste. Im thinking ok well the atomizer is reading 2.4omhs whats going on. I take it off my lava tube and use it on my ego. The First thing that happened was there was no connection the light would turn on but no vapor on the draw. So i screw it down a lil tighter and now my ego won't even fire. I youtubed some typical ego problems took tweezers pulled up on the center pin again nothing. So i figure ok it must just be a dead battery used it for a few months no biggie. So today i pulled out my other ego battery and tried that one. This is where it gets strange. So i put the protank on my ego and as soon as i go to make a draw the battery won't fire and the light won't light. ... no way 2 batteries in 2 days?!? So i unscrew the protank press the button and the battery lights up.. Its insane. Idk whats happening. Even with the lava tube at 3.0 volts i get random burnt taste's. This thing is seriously 4 days old. I have yet to try another atomizer but does anyone have any clue whats going on. My other ego batt is a goner took it apart the solder was broken so i just tossed it. My conclusion is fast tech is getting authentic garbage. Anyways this is quite a dilemma for me.
