This keyboard is fully tested and in great working condition. It is also in great physical condition. Its back-light works and it has a newly installed battery. There some very minor scratches on the top, front, sides and back. There are some bigger scratches on the bottom of the unit. It does not come with any expansion cards but has the default patches. It is missing all but two of the screws that hold the expansion card cover on. All and all, this keyboard is in great condition and sounds amazing.
