I'm selling this as I don't use it much. Please be aware that this item has some issues as noted below, and purchase with that in mind. According to Sakai Medical, production has been discontinued, so I hope this can be useful for someone who needs it. Notes (see images): * Power tested and confirmed working. * The plastic part of the plug that connects to the main unit doesn't fit well, and it easily detaches from the cord. (It doesn't come loose once connected to the main unit.) Official retail price of optional items: Abdominal belt: ¥198,000 Stop switch: ¥13,200
