This is a nice and cool accessory that I felt I want it. When I got the lens I have found some issue with it.
The most disappointing, it is not working with flash so it is useless in dark or night.
Second, the image quality is not noticeably different from iPhone lens.
Finally, the wide or fish eye are not such an interesting feature that worth to carry the lens.
Based on these problems I return the lens. If you were crazy about getting a little wider picture, you probably would like it.
