What a piece of junk.  First, it cannot pick up a signal in a place that a different Atomic Clock works fine, so it's receiver is inferior.  Second, after manually setting it, I came home to find the dial spinning.  I left it alone thinking it was searching for a signal, but it spun for 2+ hours before I pulled the battery (making a whirring sound the whole time, of course).  Finally it settled down and just holds the manual setting, but after 2 weeks the second hand stopped moving, so now it appears to be broken, but the minute/hour hand do still work.  Not recommended.
