I do not know why this say that it be so loud ... it really be not . I be kind of disappointed . I buy it for a friend who be a deep sleeper , and be hope to wake the dead with the sound , but the alarm my husband buy at Wal Mart for $ 9.99 be about 3x louder . I think the only reason someone would want this be for the bed shaker attachment ... but definitely not the alarm tone ... it be annoy ... but not too loud . I think my phone ring louder than this .
