Pro: Works great stand alone, when recording capabilities do not exceed the available 12 tracks
Con: Not as analog as it looks (like de model 16/24), but not as flexible as it's digital relative (DP24/32); be sure to check how it fits your use-case. (Edit 2021): class compliant for the 12 tracks, not for DAW control, but I don't use this anyway, I use it on Linux.
MTR capabilities are limited to the physical tracks and once you have recorded the track you can only bounce it to a free track, there are no extra tracks like in the DP24. For live use this is no issue, but when trying to layer some parts you could quickly run out of tracks in a stand-alone mode, so be aware of these limits and how they possibly affect your workflow.
It's hard to tell if I would buy it again, I would probably for this price try other options, for now I have not really had an issue I couldn't work around by going outboard, even went as far as adding a mixer/router on the subs and sacrificing two inputs (stereo) for the returns.
My use case for now was aimed at playing and recording music, in future I'd like to test the broadcasting capabilities with e.g. OBS.
