Among the effects:
The fisheye effect makes a good impression, despite additional lens much light is still allowed to pass and the results speak for themselves.
The wide-angle lens also shows good properties, but the difference from the photo without lens can be seen only on closer inspection. The same applies to the macro function - this is just the wide-angle lens turned around. However, for the very small dimensions of the lens even for purely physical reasons probably hardly possible.
Conclusion: a nice toy, in particular, the fisheye lens. Processing, quality and handling are superb! (Only) for wide angle / macro to the acquisition, however, is not worth certainly.
