As other reviewers have mentioned, this is a very good clock in some ways and useless in others. The main problem is the face of the clock is unreadable at almost any angle other than straight on.  If the clock is mounted lower than your eye level - which it most likely will be -- you can't read the time.  This seems to be a function of the way digital clock faces work.  So, it's very effective in telling time, but you can't see what time it is.  Not very useful.
