Looks good. Doesn't have discharge protection, but I would assume it just turns off when its too low to operate. Has a nasty background hiss constantly. Other then that it isn't to bad for a simple BT speaker. Has the default heavy accented female voice announcing the modes. BT Name : HW-BT (8 ohm speakers used in test, only bat power, no external connections. HISS on scope appears to be about 438 KHz, VPP of about 1v.)
