KEO: MP-833 MP4-player (2Gb, black) the ONLY slim model w/normal 3.5mm audiojack and FREE carry-on case! (audio/video playback. FM, ebook, photos, games)

Also the silicon case that comes with it has the hole at the top for the power switch on the wrong side on both units!(Latest update - Tech support say they will send out new versions with switch hole on the correct side)  Documentation that comes with it (basic but OK) states that the unit also has 3 games installed but no
