There are a lot of Aeon fans who suggest that Nitecore ripped off the design of one of their favorite lights, while others argue that it's just another version of a UI that has been used by many others.
I had an Aeon and did not like the beam pattern or tint, to the extent that I didn't even use it, selling it a few months later to another CPF'er who seemed pretty happy with it.
While I felt the Aeon was an engineering work of art, as a flashlight I far prefer my EZAAw and EZCR2w and would never consider trading their smooth, warm beam pattern for the green ringiness.
