Anyone tested or unwrapped the super cheap EBL 18650's?

So these cells are all over amazon now and they are extremely cheap, even with a charger. I am curious if they use a decent cell as compared to cheapfire and the like, and if they are true to their labeled capacity. The do not seem to be protected cells. I will probably end up buying some in order to test, if no one else has.

It appears that in one of the product photo’s of the charger there are ultrafire cells, so that gives a bit of a clue.
