Andi 4.5 ripper fully worst mobile , 512 MB Ram in this mobile so you can imagin about speed and perfomence, in this price I can buy any other best speed mobile like Intex or Micromax with 1 GB Ram. so my opinion about this mobile if you are drank or suffring any brain issue then you can buy this mobile. otherwise many mobile in this price avilable in market with high configrestion.
