I bought this alarm clock because I had another casio alarm clock before, that clock had a very very quiet tick and I was really happy with it's cheap, cheerful non-nonsense alarm clock-ness .
So, when that one packed it in, I decided to get another Casio alarm clock.. alas.. something has happened to casio.. this one Ticks REALLY loudly.. too loud in fact for me to get to sleep - I'm going to see if I can send it back as it is really un-usable for me
