I've only been authenticating with authenticate4u for a while but I've heard Bababebi specializes with Hermès. So I tried both services to authenticate a Birkin 35 X stamp purchased last year and I am so torn between Bababebi and Authenticate4u. I used Authenticate4u and they deemed it fake, so I sent the exact same photos to Bababebi and they claimed it was authentic! I asked authenticate4u again and they replied in a rude response "fine go with them" claiming Bababebi only "compares" and they don't zebra check... Who do I trust?
