I be take a upcoming exam and need a clock that help I on time control . when I receive it , it be much bigger than I think , but it be not necessary a bad thing . it be easier for I to spot it wherever I put it on the desk . what I like this clock the best be that it be silent . you do not hear the second hand movement like most other quartz clock do . I also like other feature of this clock , like it glow in the dark , and progress alarm sound , etc. . plus the price be very affordable .
