The size information was auto-generated, so there may be some discrepancies. The response to pressing the MOOD button is slightly less responsive, so the price has been reduced. Otherwise, there are no issues with the battery, operations, or use. I have added photos. Although I don't know the details, they show the various modes. No returns accepted.
