Iphone 5s was launched in 2013 with the specs that were great at that time. But its 2016 now and these specs no more live with the technology today.
People are craving to get the 5S just to show the apple logo.There are far better options then 5s in the market that to at the current price.
In my opinion its toal waste of money if you are buying it now.
It would be better to invest in a good phone.
