I purchase this clock because I do not need a clock radio . I like the large display and it do not make you jump out of bed when it go off . the only down side be that it come preset with the time . it be one minute off the real time , that be , the time on my cable box and my satelite watch . it annoy I a bit because the time can not be adjust . but it work great and be a good price . so I guess I will put up with it .
