Exactly 2 months to the day after getting it my USB passthrough from PS started smoking itself. It was working fine and I was holding it by the atomizer while I was reading here and it started getting hotter and hotter by itself. I looked down and the light was on. I unscrewd the atomizer and the light stayed on so I gave it a smack on the desk and it went out. Put the atom. back on and gave a few puffs and it works but every 2 or three puffs it sticks on and the light flashes and goes out and stays on for a while then goes out again. I have the wire taped to it so there was no tugging on it where it goes into the end. I set it down on the desk and after a minute or so I was looking at it and the light just came on by itself without me even touching it. This is the first time I've ever had any part go bad in 4 months so I'm not too upset. I'm gonna pull it apart and yank the switch out and put a manual switch on it. I've been wanting to do that anyway but I didn't want to tear it up while it was still working so its not all bad.
