Review: I love this speaker! Small size makes it super portable without compromising sound quality. The added bass you get by pressing g the button at the bottom gives you great sound when watching movies. Very easy to use and set up! Lasts quite a while on a full charge! I already had one for my classroom and this is my second one for home. Definitely recommend. I bought a case for it afterwards for travelling.
Review: Excellent speaker system! I wanted a sound as good as an Alexa, but without the internet snoopin...errr connectivity. This speaker faithfully picks up the bluetooth from your devices and plays with rich tones--high and low. I found the white Plus and Minus a bit conspicuous so I painted them black to match the speaker. One charge on the system lasts a good deal of time..I haven't found out how long yet..on my 3rd day of use!
