I have a bunch of their different models and in practice most of them are unusable today (based on ancient upstream with missing important updates; their sources are a huge mess with scarce and out-of-date docs so have fun resolving that yourself; device dtb/driver require unavailable patches; IIRC their stock vendor firmware phones out and they seem to be pushing towards a centrally managed cloud platform I wouldnt trust)
It really is a shame as on paper and out-of-box-right-after launch their devices seem great but after spending too many days failing to get working builds for in particular the Mudi/E750 while realizing that stock firmware is unsafe in untrusted networks, I've given up on them until I see some drastic change in maintenance culture.
The collaboration with OpenWrt might make the "Two" an exception, I guess, if the OpenWrt people are involved and demanding enough.
