Very good, almost in everything.

It managed to survive in the hands of a 4-year-old and a 2-year-old for 2 whole weeks. Then the microphone plug broke. It is not of the highest quality, but for the money, I did not expect anything more, for example, the recording sound on a cassette (yes, they still exist) is somewhat lacking compared to other old tape recorders.

I believe it is worth it.
For a second - portable - CD/Radio/USB/Cassette player, it is just what I needed, with the bonus of the microphone, which unfortunately only works when playing something from the Radio/CD/USB source and not at a very high volume.

Strong sound on the radio with a decent receiver, it catches stations perfectly or with minimal interference, while another well-known Brand Radio CD, with a much higher cost, does not catch them or catches them with a lot of interference.

It is not a super karaoke machine (maybe with a better microphone).
The radio/CD is perfect.
The USB is a bit lacking in sound volume but it's okay.
Portability/Size - Small and convenient - flawless.

Value for money
