3 days ago I purchased an ego one vt and it has been working perfectly fine, I was actually impressed with how well it vapes, creating plenty of vapour and not a single dry hit. Last night I was vaping for a couple mins and went to take another hit and no vapour came out, i looked at the device and the lights stayed on and the button continuously flashes, it has been 12+ hours and it is still flashing. Charging seems to work fine but the battery will not fire at all. I have tried every combination of buttons and nothing seems to work... any ideas anyone?
