It’s pretty cheap on eBay, easy to install and synchronisation between units is what they do well. You won’t be able to make anything using any of the SBCs, Bluetooth or whatever a cheaply. Most importantly, you will spend time listening to it, rather than trying to get a number of general-purpose items to not quite work the way you want,<br>
