I buy this for my sister , who could seemingly sleep through anything . it be very cute , which she love about it . I would not say that it be louder than a traditional alarm clock , but by change the pitch higher it can be much more annoying . she put the bed shaker under she pillow and say that be enough to wake she up . this get 5 star for be the only thing that wake she up in the morning -lrb- ok , 4 star for that and 1 for cuteness -rrb- .
