Avoid at all cost!
Was selling there for couple years, and never got a bad review. Last week sold a genuine item in great condition, which buyer received and claimed as damaged and asked for a refund. After asking Vinted for help I have been told that I didn't provide enough evidence that I have sold item in the stated condition, because didn't provide photos / video of item during the packaging! Are you serious? I provided photos of item just before it was sent but it was not enough.
When I have asked if I will get my money back if I will get my item damaged they said that they may investigate further and if item will be in perfect order and exactly as I sold it then I should be happy and they will not do anything about that fact! Sure Vinted, I have just lost money to post it and around 30 people who add it to their favourites and were potentially looking to buy it. Now need to get it listed and post it again if sold.
Move to Ebay or anything else. Not worth it.
