I have three, and none wobble. All are dead flat (yes, it made me go check!!!) Very odd. Does it LOOK domed on the bottom? That would concern me, since it’s an internal battery mod.Out of the box the plug was sticking out at one side. I got that sorted out. But even if I stand it on the side of the desk with the plug hanging off the edge it still wobbles. The base seems to be slightly dome shaped. It's not in danger of falling over though, just wobbles back and forth for a while before it settles down.
