As the predecessor of the same manufacturer, a slider, the display made limp, meaningful and inexpensive replacement was necessary. I came across the C 3520 and may now find after a few weeks that I have met my needs, a good choice. For me, an infrequent users and even less SMS - Schreiber, it was clear from the outset, a similar Smartfon is completely absurd and so I need a device that allows you make calls and even can write or receive a text message. This works beautifully with this phone and it may according to instruction is still a lot more, but what interests me very little extent. This mobile phone is receiving more than any other that I had before. So I see very clearly, when I have it with in my basement workshop. The voice quality is very good, the battery lasts a long time through and it has a key size in which I no longer catch two keys at once. The display has a decent size and the folding mechanism is its surface finally immune from scratches from keys or other metal objects in your pocket. In addition, the design is appealing to me. Since I am an amateur photographer and have two cameras, I do not mind the legitimate quality of built-in 1.3MP camera. I will only use them in an emergency. Conclusion: For people who think like me and so do not need the cell phone as a status symbol, the C is recommended 3520 without limitation.
