I had a friend who unfortunately had his eGo-T atomizer fail due to a drop. I cleaned it with an industrial ultrasonic cleaner, then measured resistance between inner/outer contacts. The broken atomizer: 79.7 kohms, a working atomizer, 1.9 ohms. Roughly 27500x more resistance in his broken atomizer.
As such, I asked if he was willing to sacrifice his atomizer to the gods of science, and he was willing.
I'll TLDR for everyone with a picture:
Full sized (not the greatest quality, was just using my phone) at: http://ormandj.corenode.com/images/ecig/ego_t_atomizer_split.jpg
It looks like there was a solder joint that had broken in the fall based on what I could see, if anybody is curious as to the cause of the initial failure.
[Edit: Forgot to mention, I would have posted this in the appropriate forum for consumption by those who might have interest, but I don't have privileges to do so. If this is useful, please feel free to move it there!
Secondary note, the inner core appears to be ceramic, I had to bring out a much tougher cutting wheel to slice it in half. If it's not ceramic (I don't have anything to test material composition at home), it's VERY tough.
From a design perspective, there's a lot I would change, but it isn't a badly engineered piece of equipment. I can see why the shift to a removable core with the -C variant was made, the parts with a failure mode are a small portion of the overall composition of the full part. Also, don't drop your atomizer if you have a -T, there did not appear to be reinforcement of the solder joints, and it's no surprise they fail with a high G-load.]
