I do not understand all the rave review about this useless alarm clock . Mine , when set up , buzz for less than a minute , in such a low tone that you can happily sleep through the entire time and wake up two hour later without even notice . additionally , it would be suppose , when you do not hear the alarm the first time , to buzz again at 4 minute interval : it do not . in simpler word : it only sound for less than a minute at the set time , it have a very low tone , and stop dead there , until the day after . no appeal , no redemption . you be go to be late for work if you rely on this awful clock . it be a waste of time , money and hope . I purchase it because it bear the name of `` Elgin '' , a very good watchmaker . but I go back to my `` make in China '' $ 6 alarm clock , that be reliable , humble and do not require fuss about .
