Review: Great sound, solid little but hefty system! - 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!
Review: Great little speaker. - Really fun speaker. A breeze to set up and has great sound for its size. Good for kitchen, den, bathroom or any small area, but also versatile and works great in small outdoor areas too. Will play anything on your phone or other Bluetooth source. I may buy one or two more. Highly recommended.
