I don't know if this is a replica or a original, it's new to me, have yet to see one until I search for "fisheye" in eBay. The quality of the product seems pretty good, the clip is tight, but flexible enough. The vignetting seems a little bit blurry in image mode, but video doesn't have the vignet, all in back camera mode though. By the way, I'm using it on the iPhone 4S, not sure about other phones.
