I buy two of these Chaney Instruments digital alarm clock to replace we old one . the new one be pretty , have large easily visible number and change for daylight saving time easily . unfortunately the clock have a serious design flaw . the little vent for the alarm speaker be on the bottom of the clock . with the clock set flat on a night stand the sound of the alarm be so weak it can hardly be hear . really , it be so anemic I have to hold the clock up to my ear to hear it . in fact , I set my clock to go off this morning as a test . the alarm do not wake I up . one might think the moron who design these clock could have guess that put the alarm vent in a spot where it be cover up be not a good idea . I see some complaint about this problem with a weak alarm sound in the review , but think they might be exaggerate . they be not . this thing be a dud as a alarm clock . you would be better off buy a rooster . at least you could hear the crow in the morning .
