I will share my experience about Ebay.in. I was buying the power bank, then I check some power bank in ebay, there are various type of power bank available. I liked one model but that model have various type of price of same power bank. I was very confused which one is genius or which one is duplicate. I call the customer care, but the customer care executive was busy, not attending the calls. Ebay sell both duplicate and origional product but thera are confusing which one is genius. The quality of product is poor, because they not clear it. The ebay delivery time is good, but the delivery location is not available in more location. The app and website takes very much time to loading it. The product reliability depends on the seller is good or bad.
