I have purchased a redmi 3s 2 months back.The product quality is good, packaging is also decent considering price and it is a original product.Delivery takes 2 days to delivered to the destination.Till now I didn't faced any problem with flipkart.This is my third purchase from flipkart and I faced no problems with that.Surfing through flipkart is also a good experiance, Sometimes browsing seems to be not good because of internet connection but it is not his problem.I also use the application.Giving me a good experiance, simple to use.Flipkart is reliable because it is a very big and reputated company Sometimes it is by mistake or sellers bad intention to sell the rejected or firstcopy.But it is a big company so dom't be scared of being fooled or cheated by company
