I love the clock . I buy it to replace one I have at the end of we family room that have digital number that be 5\/8 '' high . even with new correct prescription glass , I be have trouble read the number on the old digital clock . this clock , no problem ! I could read these number half a football field away . however , I find after a couple of day and evening , there be something about the clock that be annoying I . at first I could not figure out what it be . then I realize what be bug I . it be the constantly flash colon . it seem so domineering . it be like it be demand you attention . there be no way to turn it off . but I find a `` work-around '' and what a difference ! I trim two small piece of black electrical tape and very carefully put they over the colon so the colon disappear and you can still see all of the number segment just fine . now it be great ! not nearly as intrusive . maybe the flash colon will not bother you , but if it do , now you have a solution . I be very happy with it now !
