There are no operational issues, such as power-up. While there are no major scratches on the main unit and transmitter, there may be some scuffs, minor dirt, and dullness. Please check the photos. Accessories include the main unit, transmitter, and a charging cable, but I'm unsure if this cable was originally included at the time of purchase. Please understand the above and purchase with no claims and no returns.
