my mother want a clock with number she could see at night . the extra large number , the largest I could find , be very clear from across the room to she . it be use also as a sort of `` night light '' to see about the room if she have to get up in the night . you also have the option of dim the number if it seem too bright for you . Easy to set alarm , and shut off which she love . at a very reasonable cost it be a perfect gift for the senior citizen or anyone who have difficulty see .
