this be a great travel alarm ! it be exactly what I be look for . it be tiny -lrb- 2 1\/2 '' x 1 3\/4 '' x 1\/2 '' -rrb- and the alarm be loud -lrb- I sleep with ear plug , so I need something to wake I through they -rrb- . however , I can not imagine it would be too loud for those who do not . it be very easy to set and the night light be bright . and the price be right . I be very , very satisfied .
