Yeah, I have one. It's way better than FM quality from radio stations, but it's not full CD quality. It uses a higher frequency range than broadcasting stations and obviously it's much closer to the antenna, that's why the quality is higher.

I've only compared it to FM on short trips to Sweden though, since FM has been shut down for years here in Norway (except for local radio stations), so my experiences may be positively impacted by the mostly interference free life here. My car speakers aren't exactly high end either.

Worth a buy regardless though, it's really nice to be able to listen to whatever you want without planning it beforehand.

Yup.
