It’s pretty good. It does a few wonky things, but over all it’s pretty good.
Edit: specifically, sometimes it doesn’t boot up and I have to unplug and try over and over to get it to boot up. It’s done this when setting up at gigs and it’s stressful. Lately my main ‘fader’ has been sticky/jumpy. And less shocking, but a drag, is you lose 2 channels in if you want to run an effect on aux, like reverb.
