in great condition, everything works, The one thing that needs mentioning is when I turn on the power switch it sometimes doesn't power up right away, it may take couple of tries. it doesn't happen all the time it's just random.
I keep it on when i need to use it for a project, otherwise it gets stored in the original box in a climate controlled room.
Tascam will replace the switch free of charge since it's a known issue.
I just didn't use the mixer that often to need to send it, but you can defiantly get it replaced if you want to.
