The sound reception like all other chinese phones is really bad.
I have been using it for 3 months and it has not been hanged till now.
The style is really good with a good size but it does not possess a matt finish at the back to allow a good grip.
The features as listed are awesome but not on the real side of it. I have installed only 500mb of apps but still I have only 1013mb of ram left out of 3gb. That has been quite a drastic experience.
Now talking about the durability is a no-brainer because a chinese phone can never be durable or be trusted for that.
Its an average value for money because you have to compromise with brand if you want to have all its features.
