This is the bedside alarm clock with a dimmable ambient light that turns on automatically when you flip the clock over. As you get ready for bed, the light produces a soft and cozy glow to help you wind down for a restful sleep. Flip it over and the light turns off. Once the alarm sounds, flip the clock again and the light gently helps you awaken fully. To snooze the alarm, give the clock a shake or press one of the buttons surrounding the clockface. The clock has an ergonomic design with easy-to-set buttons for dual alarms. The clockface’s backlit display illuminates the time at night and can be turned off for light sleepers. Built-in battery recharges via USB. Charging cord included. 3 3/4" H x 3 1/4" diameter. (5 1/2 oz.)
