1) Good sound quality. I will not say that the sound quality is like Bose speakers, but is resonable good for this price point (please watch videos with sound from the speaker)
2) I gave it to my 3 years old grand daughter. She absolutely likes it. The dynamic led lights, sound, mike size, and everything.
3) Its light weight and of good size.
4) Connecting with phone or computer (via Bluetooth) is straight forward and flawless. Also connecting the accompanying 2 microphones is a breeze.
5) The battery lasts for about 8-10 hours, which is quite good.
6) The mcro SD card slot also works great. Just transfer songs on a micro SD and install in the slot.
Overall it is fun for everyone but speciall yonger children.
