Build quality
Robustly built, very clearly laid out.
As far as build is concerned, the only thing I'm not crazy about is the power adapter which seems a bit flimsy (the plug is replaceable and not very sturdy).
Usability
Workflow is as I expected having, in ancient times, worked with a Yamaha MT4X portastudio, and a great relief compared to the inspiration-killing sadness that is a mouse and keyboard and having to wrestle with drivers, windows updates and popups. Do read the well written user manual before use though - this machine does have relatively many options and you shouldn't expect to be able to work with it without any reading.
Sound
The 24 bit DACs should provide enough headroom to avoid ugly digital clipping with a clear margin.
Compared to my Focusrite Sapphire 2i2, the input sensitivity on the Hi-Z (guitar) input is actually sensible, meaning a P-90 singlecoil cannot overload the preamp with the input gain turned all the way down.
The built-in guitar amp simulator sounds weedy and is only good for hearing something resembling an electric guitar while recording a DI signal. I wouldn't use it for any serious recording, ever.
In summary, a good sounding, well built machine which, after just a bit of time studying how it works, is great fun to use and does not get in your way.
