this thing will wake you up even if you will not wake up for a fire drill . the vibrater be great because of the long wire . the rainbow color number will get you you friend want it too ! it light up the night . the light be kind of bright , so if you use a night light the alarm clock will probably be use as the night light . but if you be use to a dark room , you room be go to be a bit brighter than usual . but I be personaly impress with the alarm clock .
