I've tested it several times. The text on the main unit is worn due to being carried around for a year or two. Ultimately, I didn't use it. The earphones and charging cable are unused. The box has discoloration due to aging. To reduce shipping costs, I will fold the outer box and include it with the product. I will lower the price accordingly. Thank you for looking.
