The card is compact and easy to take with you. It is not entirely clear why the obsolete usb B connector is installed, it would be more logical to use micro usb. Contrary to all the reviews, it started up on my win10 without problems, installed the drivers using the links from the reviews, picked up the device in FL Studio - the flight was normal. The sound from the line input is clear, without extraneous noise. The output sound is noticeably better than the laptop's built-in sound card. Great for recording small projects. I also want to note that this model works with an android phone via usb-otg, both in playback mode and in recording mode.
