I have been using flipkart for past 1year and ordered many eyeglasses from flipkart. these glasses are mostly duplicate ofcourse they give them to you at low pricing but eyewear from flipkart is not durable.in case of earphones I never got the one I ordered they sell a lot of duplicate samsung products so I recommend not to buy any product of samsung company.delivery is quite good they take max 7 days to deliver your product.refund is also good.but they sell many duplicate products and most of the time never get the same product that we ordered for.thankyou.
