Operation confirmed. I purchased this on Amazon, so the main unit and accessories are in good condition, but there's a label on the box that I've tried to remove as much as possible, so the condition of the box is poor. Please refrain from purchasing if you are concerned about this. The main unit and the USB cable for connection will be included in the box and shipped together. Please note that a cannon cable for microphone connection is not included.
