I noticed another user concerned about the device causing a fire. My device froze and overheated and may be a fire hazard now. I am storing it in a bag designed to contain Lithium battery fires, luckily I had one already from R/C stuff..
Hope this helps anyone else who is concerned. I am still waiting to hear back from these guys, the retailer I bought the device from believes their distributor will not accept this device back and I personally will not ship any potentially hazardous materials.
My MiniVolt got very hot after I plugged it in, smoke poured out of the charging port, I unplug and there is no charging port, just an empty hole. It burned right off the board and no more vapey for me :(
I overnighted the unit 8 or 9 days ago, really hope I get a replacement soon
