as other have say , the best thing about this clock be that I be able to see the huge number without my glass . it be also nice that the time be automatically set out of the box . I do find the number to be a bit too bright though . the real problem be that on arrival I notice the number on the clock be flicker a bit . not too badly at first , but definitely noticeable . in the middle of the night , the clock wake I up by make a high pitched whining noise . I pull the plug and return it the next day . at least the return be easy , and I buy a different clock that I end up liking better .
