This is a MOTU M2 audio interface. I used it for about two months and have kept it in storage since then. I'd like to sell it because I no longer need it and don't have space for it at home. It's practically new, as I didn't use it for very long. There are no noticeable scratches or stains. It works perfectly fine. Although it's like new, it is a used item, so I would like to trade with someone who understands that.
