I am using quikr app. till date I had a good experience. I had put a product iphone 4s for sale on this app. in just one day I got 3 to 4 good offers for my old device. my pesonal opnion is that if you want tk sell anything on this app then you keep genuine price as per condition of the product. you will see some good responses. one more thing you go for primium add in that way your product will be sold earlier then free add.
