I got this device so I did not have to go through the line in on my pc for recording with a yamaha mixer I have (the main purpose of the mixer is for voice over levels when I occasionally stream). The TS Mini has given me so much more than that though. It may not be "plug and play" for Windows, but no audio interface is. There is a google drive link for the driver for it, but I honestly don't know why it isn't hosted on the website. That plus the button for which channel of the direct input you want to listen to could have had an extra led or a multicolored led that changed colors depending on which channel is selected are the only reasons for this not being 5 stars. A nearly perfect product that does its job and does it well.
Also, for iOS users, I was sent a Y-Cable from MeloAudio to connect to my iPhone. It was sent in another package that arrived a couple of days later (not something I ordered or paid for, nor had I asked for it). Hopefully this is something they are adding to every order but I do not have confirmation on this yet.
