This is really huge dna od called VT 250. We all know VT family from Hcigar company. Well this one works with 3 18650 batteries, has dna 250 chip, 250 watts, massive springloaded 510 connector and very unstable bottom standing part. At all it is big working device, but not MUST VAPE. I still do not have classic issues like problems with paint or weak 510 connector.
