Summary: My YP-K3 is 2 years old, and it's unusable now. The display started getting dimmer about 6 months ago, now I can't see it at all. You can't operate the thing unless you can see the display, so it's useless. I checked on getting it repaired (it's out of warranty), and the estimated cost is $85.00.
Summary: Loved it at first but the playlist function does not work. You are suppose to be able to create an album out of whatever songs you have in your library and when you transfer to the unit, it should show up in your Playlist (according to samsung support). This did not work despite several attempts.
