well, mine didn't necessarily die - they just went wonky. the first one went all voodoo and the LED lit up while attached to the att just laying on the table. I got to it too late and it had super cleaned the atomizer. bleh! It then proceeded to randomly turn on while not attached to anything. It's possessed
The replacement that came for it had similar problems but not identical. I believe the switch is just sticking on this one as the LED will stay lit after I've stopped drawing on it. Then it will blink and either go dark or stay on. A quick puff of air turns it off.
