I had to look far to find even a useful clamshell. On the market there was only Simplest phones or unaesthetic seniors phones. The Samsung C3590 is still a real clamshell and has everything you need to make phone calls, including Bluetooth and Web browser. It makes an excellent tactile and sophisticated look. The key pressure points are very good and the keys have a reasonable size. The display is easy to read. For this purpose it has an extremely low radiation value, about 1/3 of my old Nokia.
The only drawback is the limited selection of preprogrammed tones. This may, however, via external Micro-USB cable on the special Samsung software (available for Mac and PC) to be recharged. Also can be used as an MP3 player with an additional memory card, the mobile phone.
