I sell and buy almost exclusively on vinted and almost never have any issues. Of course sometimes there is a large delay in shipping or so, but usually it gets resolved. I always loved vinted personalisation feature and had a lot of good recommendations. However, recently I started getting absolutely random sizing in my feed, even though I only have "M" ticked, kids clothes, random technology I never need, and just clothes that are not personalised at all. I am not sure what happened to vinted's algorithm but I hope it is fixed soon.
