Review on 🎧 Wireless Audio Receiver with aptX Low Latency - Bluetooth Music Adaptor for HiFi Speakers/Home Stereo/Headphones/Portable Speakers - Enable Bluetooth on Your Audio Devices (MR230) by Eric Teshome

Working. Does not turn on automatically after the battery runs out, the switch is turned on and connected to the network (you need to turn off the switch, wait 10 seconds and turn it on again). In other words, you can't just leave it on and always on (when you turn on the machine, the device turns on). The range is pretty terrible too, about 3 feet; Anything over 3 feet will be very choppy. The sound quality is not great at all, although not terrible. For the price, I'd say it might be worth it in some scenarios, but I've seen cheaper options that would probably be just as good as this one.
