I have bought my unit in may 2022, since then it was working perfectly till in december it bricked. Thomann support was fabulous and I got replacement unit without any hassle.
Interface feels very nice and polished. Hardware-side of it - looks slick, connectors are working properly and hold tight, knobs are not wobbly.
Software-side is a bit downletting in a sense that we get awesome 8channels out (main, mix3/4, mix5/6, mix7/8) and ADAT 1/2 3/4. we get a lot of audio-ins, but routing is basically non-exitstent. My only other problem with it is you cannot write down volume, use the slider only, which once touched, cannot be resseted to 0db anymore, so if you have problems with putting exact values on each track, then ye - not the gear for you. I overcome it, but irks me still.
Other than that - its a nice device, it does the job well for what I do - hobby livelooping and beat making to myself.
