I have bought to my brothers this mobile so as to use it roughly and regularly. I found this mobile in my family members hand and he use it in such a way it will not get diacharge its battery. Because he doea that much phone calls in his daily life. The mobile which I bought for me first and use it without any tension of battery, sound, etc. Its supporting memory slots too. So we can use it to store sounds, ringtone, etc. Also earphone slots available. Its case is a good quality case with strong plastic body. Really go have this mobile if u are rough caller.
