This is a cool little clock that looks a lot more expensive than it actually is. It's 7cm (w) x 13cm (h) x 5cm (d). It has a bright blue back light that makes the digits very clear, with the light button the biggest out of the 5 to make it easy to find and press during the night. The actual display shows: Time (24hr/12hr), month & date, day, plus the temp in either C or F. You can either set the alarm clock to ring once, or use the pre-set snooze alarm which will go off as normal, but then go off another 3 times after that, no more no less. There is no snooze button however, so you must pre-set this function to use it. Otherwise the alarm will only sound once. Another little extra is that you can set the alarm to ring a "Happy Birthday" tune to go off on your birthday, instead of the standard one. The unit requires only 2 AAA batteries to work, however if you want to use the back light you will need a 3rd battery. All in all a very good expensive looking clock.
