" ...  I bought this to replace my old alarm clock that wasn't as bright and the numbers were smaller .  ...  "
comment
" ...  I like pretty much all the features of the clock as it pertains to clock functions. ... The beeping of the alarm is loud enough and it's great to be able to adjust the time for the snooze alarm clear up to 60 minutes (I like about 17-20 minutes), as well as the highly adjustable brightness. ... The clock is also extremely lightweight. ... The vendor contacted me about my review and offered to replace the clock. ... I had not returned it because I love the clock so much just as a clock. ... I guess the first clock was just a fluke(& it's still a great, working clock). ... The clock is placed near her recliner & she can actually see what time it is now without having to ask.  ...  "

" ...  After looking at numerous clocks, we landed on this one not only because of digit size, but because the display color looked to be a nice comfortable green ... blue would be nice, too, but the green is very easy to look at when the display is pretty much all you see at night. ... The face is perfectly flat with a very small bezel.  ...  "
