Samsung guru is More reliable and durable phones because of its small pocket size structure . I am using this phone from 3 years there is no defect till now . I think its a great deal to buy this phone .
It does not have cool features like a smartphone but at this price the phone is good .
It has a long battery life . yeah trust me once I charged up the phone can work for 7-10 days longer without charging .
For calling or messenging purposes the phone is fast and very reliable .
