Has anyone ever used poshmark concierge authentication?

I'm thinking of purchasing a Celine tie tote but am unfamiliar with Celine and wanted to know if concierge authentication is reliable?

I've heard varying messages of disgust, despair, and outright hilarity concerning Poshmark, so I'd steer clear. You'd be much better served by getting the Celine authenticated here, in our very own Celine 'authenticate this' thread.
