Joinmarket.net (discussion) experience?

[examplens]

Does anyone have personal experience with Joinmarket or at least experience from a reliable source?

After the departure of Samurai and Wasabi wallets from the Coinjoin feature, Joinmarket seems to be the only remaining "free" option.

I would like to get feedback from someone who has used JM. How safe and effective is it in general?
What are the pros and cons here?
Is there a risk here and can developers be prosecuted by the feds?
