I received the X Cube 2 about a week a go. All was good until one day I set it down on the desk after I was done vaping....locked. All of a sudden I hear a hissing sound so I reach over to grab the vape and it was smoking from the bottom of the mod. I picked it up thinking it was fireing but it was still locked and would not fire when I pressed the fire button. Then came an awful smell so I took out the batteries then replaced them later. Now all it does is read "ohms too low". There's my little complaint. So if you decide to get the x cube 2....don't buy off of Craigslist or from a friend....make sure you buy it from a trusted source so you can get your warranty.
