1. With the fisheye lens can be good at making party photos, to make them look a little more artistic.
2. The Macro lens is suitable for ultra-close-ups. Both in nature and at home can be very interesting to shoot close-ups.
3. The wide-angle lens can be made good group photos
4. The telephoto lens brings sights and housing closer to the camera
It is worth mentioning that the wide-angle lens is screwed onto the macro lens. The other lenses are throughout.
Each lens has a protective cap and the processing is much better than expected for the price. Through the built-in magnets can be the lens at any time simply remove.
All in all, well worth the investment for private and holiday pictures definitely. It's fun to try the different lenses and since then I have the lenses, I photograph again more with the mobile phone camera.
PS: You should a cell phone or similar with metal lid who otherwise keeps the magnetic lens of course not on the phone. At the company's mobile phone (iPhone 5s) the lens keeps well, the Galaxy S5 not, as this is made of plastic and has a bulge.
