I am trying to be fair. I have used zen stream for almost two years. The initial setup was a bit tricky, but anything has its learning curve. Once setup, it worked quite smooth. I do have to restart it once a week in average, but I didn't experience most of the issues stated here.
For the Chromecast and qobuz support, it's a bit pity. However, this might be the only product on market that support Roon and NAA at this price point. If you use Roon, Chromecast and qobuz are no longer issues. I believe a large group of ZS users are buying it because of these features, not mentioning others like Tidal, Spotify, wireless, etc. I see most properly priced used units sold very fast on used market.
In terms of SQ, it sounds better than a couple of other streamers in the same price range to my ears (could be a personal taste). It's not a perfect product, but I definitely look forward to improvements to its next generation.
