first , I love this clock . I love that there be no cord and that it do not light up until you push the top button to see the time in the dark . the only downfall be that it initially get we time-zone correct at my office and then change itself to a incorrect time-zone when I take it home ... the weird thing be that we be no where near the time-zone its display . so , when we look at the clock - we know to add a hour for the actual time . a little annoying , but I would still purchase again as this seem like a minor flaw that we have learn to work around .
