I ended up pulling it apart. The little atty heat coil was completely black and pretty much flaked apart when I touched it. The built in wick was also burnt up.
I'm not sure how I fried it, since I was putting in fresh carts all the time and dripping a drop or two on the wick whenever I would replace the cart.
I am chalking this up to a crappy knock off. I have 2 other atomizers that are 3-4 weeks old and had a good amount of use with no problems.
