Very adequate as a low-cost amplifier!! But... can't figure out how to tune the FM radio??? No clues in the manual. If that would work, the rating goes up to 4 1/2 of 5. Possibly the 'auto' search isn't working. I don't know.
The sound quality is great thanks to its 200w Max power output. I love being able to listen to all of my mp3 albums from my phone. I also like that it accepts USB flash and SD memory cards which I can load full with songs. Great Unit loaded with features!
