I am writing this as a end-user for iphone 5C.
As compared to 5S, it is much cheaper and with almost same feature. With Apple brand name and its service this phone is definately a must buy.
Only problem I am facing is its accessories are very expensive(original) and local products for 5C is not available easily. Like I was looking for back cover, didn’t find that. I had no option but to put cover.
Features like Facetime, imessage, siri etc are really unique for iphone
