This is the RM-1S model remote control from Nakamichi. It is the original remote, and has been tested and it is working and producing the infrared signal as it should. It is clean and does show some light scratches and wear from normal use. The battery compartment is clean as well, with light wear on the terminals. I show a number of photos. If you are not happy with it, I am happy to take it back. Free Priority shipping, and it will be packed well.
