this clock do not use 1 c size battery . I require three aa cell -lrb- operate on 4.5 volt -rrb- . also , clock face do not face forward . it be pitch upward by about 20 degree . this be fine if you be look down at the clock . if however you place it at eye level or on a shelf above you head , it be go to look stupid . the back-lit dial face be useful if turn up all the way . rear of clock have time and alarm setting knob , battery compartment , alarm sound port , and brightness control . the top have a combination snooze alarm switch and momentary bright light switch . the right side of clock have alarm on\/off switch . there be no rubber foot on the bottom of clock so it slide easily . also , the plastic housing be static prone and attract a lot of dust . there be no model number stamp or emboss anywhere ; battery door say `` make in China '' . all in all , not a bad clock for ten buck provide it keep work .
