I absolutely love this alarm . I be one of those people who sleep so soundly that I can hit snooze or even turn my alarm off without even know it . I buy this alarm because it have a vibrate feature , but I be pleasantly surprise about two other feature . first , there be flash light that help you wake up . second , you have the ability to change the tone of the alarm . I love this feature ! I have always avoid the buzzer on most alarm because the tone be so annoying . this alarm let I change it so I can use the buzzer . one thing to be warn about : you can not turn off the flash light . I do not mind that . I like the light . but , I can imagine it would be annoy for some people .
