I'm not a big writer of reviews, only here I must really say this product is a disgrace to Brown. Had I chosen especially for a brand and am disappointed. Can definitely not recommend this product. Have bought the alarm in August 2011 and relies on the alarm. After I use the alarm clock just to make sure, if I have to get out very early, at first I was not checked the alarm. When he woke me time and time not (once I had overslept and missed the plane), I was taken aback swapped the batteries and also to no avail. Because the warranty has expired, I use it only as a clock because he is reliable.
