I got this last time and there were only two lenses in the case. The box never said anything about three, either, and seemed to only be set up for two anyway.
Oh man, sorry to hear that. Did you happen to email firstname.lastname@example.org with your issue?
I got 3 lens. Two of the lens are screwed together. Tried it out on my iPhone 6plus. In portrait mode the lens work correctly, but in landscape mode two of the lens shows the ring of the lens. Not exactly what I was looking for
