I have bad eyes and needed a clock with big numbers. This clock works fine. The numbers can easily be seen across the room. The description states the numbers are green, but they are more of a avacado green, almost yellow. But that works for me, makes the numbers very visible. The dimensions of the face of the clock are 7 3/4" across by 3 1/4" tall. The numbers themselves are 2" tall by 1" wide. There is a hi/low dimmer for the lights. My only complaint is that its not as loud as I would like. I like my clocks really loud, so I don't miss school. I would rate this clock as being medium in loudness. Which is okay because some people prefer a less intense alarm. I haven't missed school, yet. The durability is the same as any other clock in this price range. Overall, I'm happy.
