Same model as Bisq. I use it very often and never got problems.

The seller "locks" the sats with a hodl invoice before the buyer sends the fiat, so the seller can't do fraud. The only risk I can imagine is that the buyer does a fiat charge back, but that's not possible with most payment methods (sepa instant, revolut, wise are all final and not able to charge back). If there are complications the hodl invoice and the bonds will be locked and the mediator will collect evidence to decide.
