...not brilliant. I don't wish to sound like a moaning minnie, but I've been looking for a utility that would just allow a little customisation of the built-in clock. This was close, but no cigar unfortunately. These are my reasons for deciding not to use it:

1. Clicking on the clock to make it drop down is very difficult - it doesn't seem to work as a menubar item should, nor does it highlight properly. If it were somehow integrated with the main OS one, it would have worked better.
2. It's a shame it's an app instead of a prefpane - I think a prefpane would have been more appropriate.
3. Size is not very accurate. I was hoping for something about 1-2 point sizes smaller than the OSX menu clock, but all I can have in that range is Normal (too big) or Tiny (too small).

If none of these things concern you, then overall it is a decent solid piece of software with lots of customisation options.
