I use mine several hours in a row, out in my garage where the WiFi signal isn't as strong as it is indoors and haven't had any issues with it--I typically use Pandora out there as I'm working. If WiFi is weak, Google used to sell an Ethernet adapter that worked alongside the USB power input. I've streamed Qobuz 24/96 to the garage with no problems, or will fire up Roon and send hi-res titles to the garage with only a rare hiccup every so often. The CCAs in the house all work with no problems. In fact, I play three CCAs, two hubs and two Nest Mini speakers as a group while I'm working in the house and they rarely ever give me a problem.
Streaming problems are most likely due to WiFi quality and signal strength. Ever since I upgraded the house to an enterprise-grade WiFi access point, everything in the house works so much better.
For casual/background use, the audio output of the CCA is fine. Since it does have an optical output, it can be fed into a DAC if using in a better system. It won't outplay streamers costing hundreds or thousands of dollars but for its cost, it does a respectable enough job. (I bought some of the last batch available at $15 each...so yeah, seriously, I will never expect the ultimate audio quality from something that cost so little.)
