Love the sound quality and portability of this device! Only issue is if you leave the bluetooth on, the creepy computer voice tells you it's connected to whatever device you have in range. Which is not so great at 3am when it announces that it's connected to your phone. Strangely, hitting the power button did not silence the machine. I assume you have to turn off bluetooth to keep the machine quiet. Anyhow, be aware that the speaker will talk to you at any time.
