i bought the vivi from MVS, read around this forum that they were reputable
i also bought the evic from them, and after scratching the serial number on the box and entering it into the joyetech website it came back as genuine
the 1.8 is reading as 2.4 consistently
if i get my hands on a multimeter how do i use it lol?
what do i connect it to on the vivi?
A multi tester is a "must have" for vaping. Takes a lot of the guesswork out of diagnosing problems IMO.
