Hello Friend,
I bought this mobile Redmi 1s in September 2014, I must says that it has a powerful performance for this price range till date as due to regular update from the company, mobile gets the best output considering the hardware it has.
I know it has been taken over by its successor from the same brand which are much more impressive in term of hardware and software configuration. As the technology grows every second its time to move on but still we always remember those old things in our life who are value for their money.
Hope this feedback would be valuable in the long term for the new and advance technology.
Thanks
Shaz
