We are very satisfied with the cell phone. The menu system is easy to understand, everything can be well adjusted. After inserting a micro SD space for custom ringtones is in MP3 format. The volume from soft to loud well adjusted, press the buttons easily. They remain illuminated in blue. Write SMS is not a problem.
You can on the display set a background image (own photo) and assign the callers photos.
All in all, the phone comes over very valuable.
It might not be as stable as some other devices, but I think it holds already :)
