I bought this 3month ago for my dead till there is no fault, working smoothly Samsung guru e 1200. It is known for long battery life although it comes with only 800MAH but as compared it's screen size it's enough to maintain power, next thing I realized is that it's durability, really it is made very hard and strong material. If I say anything about it's vibrator it's amazing. It's comes with an 1 year warranty and also with SAR certificate. Allover mobile is very good as compare price( 1100) .
