It cost about £60 and is supposed to be self-correcting re' the time, so you never have to set it. Anyhow, I woke up this morning at "5.30" and thought, crikey, it's light. Then I dozed off. I woke up at , ahem, "5.30" and thought "I'm sure I've been back to sleep". And then I thought "I have been back to sleep" And then I thought, ". It is 8.55".
I am quite impressed that I managed to get DS, packed lunch made, karate kit in bag, breakfast inside him, to school within 40 minutes. I am not impressed by the alarm clock though.
