I purchased this phone for my office use and battery backup purpose and in my office smart phone not allowed . I had seen lot of phones but lastly I bought it in the month of Jul 17. Till this time it is working in perfect condition, battery backup is 3-4 days if you talk on average basis, just one problem when you try to listen FM radio on long basis it will give only 2 hrs battery, its little sad but allover it is best phone in its range. And you have to pay very less bucks for it like only Rs. 1150/- only.
