Inexpensive mobile phone, battery lasts up to 3 weeks

Since about 5 weeks I have the Samsung E2600 in use. I like it very well and I am fully satisfied with it. For a family member, I had ordered the same phone and he is very happy. We have the only mobile phone to make calls and now and then for a few SMS. We have deliberately decided against a smart phone and a mobile phone, since the battery lasts a long time and we "always with a" small, lightweight cell phone wanted.

+ Battery lasts in standby mode from time to briefly call more than 3 weeks
+ Slider phone goes perfectly
+ Voice quality properly
+ Very good to understand, even with a recieving
+ Handset volume
+ Bluetooth
+ Immediately connected with my TOMTOM
+ Easily about 90 grams
+ Small
+ With my EDEKA Calling Card (D2) even in the concrete basement very good reception
+ According / loudspeaker
+ Charging cable with plug part here

- Understanding of speakers is not optimal, since no full-duplex
- Any detailed instructions available, even in the Internet
- Only one quick guide here

Still 5 points, since I do not have to conduct speakerphone calls and also was able to close without detailed instructions the phone. I would again buy me, so it can recommend in good conscience.
