All the products are not genuine because anyone who has product either duplicate or used can easily sell on this website.
There was when it was the only website to buy a lot of products online but due to it’s easiness of selling on it, it has become a troube for buyers. There is no gurantee for originality of any product.
Above all that the worst is their customer service which is the slowest among all.
There app is no special at all, its same as the website.
Thus the time gone when you can trust and buy through ebay.
Amazon and flipkart are doing a great work, try them.
