I have be oversleep on workday for the first time in my life - sleep through alarm . now no more worry . this really do work , and I find it very cute too . the sound be adjustable both in quality and volume - and the shaker really work . I be very grateful . it be easy to set both the time and the alarm . one reviewer complain about the brightness - and the number be bright during the night and change color , but I like it . be just hope that I do not annoy my neighbor , so I not set on the higher volume . this be definitely a very girly look clock . I have purchase three altogether - one for my bedroom , one for the living room set 20 minute later , and one for work - just to look pretty and keep I in touch with the time . you can can a visual alarm with a small row of light flash if you do not want the sound . I also purchase a extension cord which work fine . I be very pleased with this clock !
