Start your day off with a buzz as opposed to a siren. Simply set your desired wake up time and place under your pillow, to wake even the deepest sleeper without disturbing your slumbering partner. Can also set an audible alarm and has a dual alarm setting feature for use with two wake up times. This little gizmo is especially helpful for those with hearing limitations, shift-workers or anyone who sleeps using earplugs. The slimline design makes it the perfect travel alarm clock with date and temperature as well as digital time on the backlit display. Place under your pillow and the alarm will wake you by vibrating. Helps visually or hearing impaired as this is an alarm you feel.
