I really like: the size and weight of the unit, not bulky or heaving; the sound - decent speakers and no echo; the lights; and the way the songs/videos pull up on our TV (hooked up via USB cord).

The unit’s top and bottom flashing lights look great in a darkened room and add to the party atmosphere (they can be switched off, too).The microphone and speakers are probably the best parts of this machine

Good sound quality and easy to use, and the lights are kind of neat.
