Specifications:

• 3 PROGRESSIVE VIB & VOL:Unlike regular alarm clocks, the volume and vibration of this loud alarm clock begin off slowly and softly before progressively increasing till it reaches its maximum--86 DB. The gradual sounds adding for a bit of urgency, and then wake the whole house. Level 1 vibrations might not actually throw you onto the floor, but level 3 will certainly be strong enough to jostle you awake. Don't worry that this loud and powerful alarm can't wake you up!
• AUTO DIMMING:This loud alarm clock for heavy sleepers will automatically adjust its screen brightness according to the environment's lightness. No need to manually adjust the brightness every day anymore! The LED digital screen becomes brighter when there is a strong light in the environment. This is definitely a lot less hassle than other vibrating alarm clocks, especially for the elder and children.
