Lazada has the best customer service and most items can be returned, even if you just change your mind.
I received an item that was broken and could be returned, even upon change of mind. I was about to travel, but still had time to print the label and go to the shop to return the product. However I received the message, that the seller would consider my return request and get back to me within 3 days. After I left to travel, the seller accepted my return request, but I had to return the item within 7 days, which would not be possible, since I would not be home by then. After I returned back home, I called Lazada and explained the problem. The customer service agent didn't even hesitate and swiftly extended the return date.
