POS. Bluetooth has never worked. Get red light sometimes, charge it for days; does not matter. Get blue light sometimes, also doesn't matter. On-off button - exactly what does that do (sure doesn't turn it on or off, just curious). $100 POS. But to be fair, my curiosity got the better of me & after a dozen or so resets, plug & unplug, make sure I understand basic concepts, etc. - or said another way an hour of utter anger / amazement it'll work with a direct cable. Gonna make a video of this thing being destroyed so I never again waste my time - to get a speaker to, well, speak. Who knew all ya'all were that far ahead of the curve.
