It’s loud, easy use, but auto-reconnection/pairing is weak.
I like it. I’ve tried Fosi, Mii Audio, and Douk Audio amplifiers. Only this BluAmp can power a passive subwoofer, of the four small amps. It can power a subwoofer with 50 watts, @ 4 ohms, not sure about 8 ohms. My speakers are 4 ohms, and 6 ohms.

One sick little amp!
This amp is outstanding! It gets much louder than I expected – truly impressed by the design and sound quality. Was not expecting the tactile/haptic feel of the knobs (they feel like stepper motors). Love it
