The unit functions without any particular issues. Included are the original box, instruction manuals, remote control, AAA batteries, power cable, USB cable, and RCA cable. While there is some evidence of use on the exterior, there are no noticeable scratches, and I believe it's in good condition. Please check the photos. This is a used item stored by a private individual, so there may be other oversights. Please refrain from purchasing if you are sensitive to such matters. The original box will be wrapped in bubble wrap for shipping.
