Like several others reviewers, I also missed the fact that this item does not have a battery backup! I bought it because I thought the CD and mp3 functions would be pretty neat. Never in a million years did I think that it would not have a battery backup. It is an alarm clock, after all.I would return it if it wasn't such a hassle. Plus, I did give it 2 stars instead of 1 because everything else works good. It is a nice little radio, just a poor alarm clock. Maybe I will plug it into my computer's battery backup if there is a spot.
