After too much research I purchased Panasonic GD35. Initially I was skeptical whether it will deliver what it promises. But now I am very happy. Battery life is very good. I charge it twice a week. Too many ringtones (20), personalized ringtones, better SMS, better talk time all these feature make it very good value for money. Size is small and weight just 109 gms.
Calculator and Vibration alert are very good. Alarm and On/Off timer are great features. It can extend battery standby time a little more. It matches almost all specifications given on the brochure.
I am very happy with my feature rich and pocket friendly mobile.
