with an LED display they should last a while.

Too big to be travel size, too hard to set alarm times, dim display even when ligth.

Great size and great display options.

The display is very sharp and the contrast is excellent

The display is clear and easy to read.

This little clock was inexpensive, has a good, clear display and provides all of the information I was looking for.

Had bad display, only partial numbers was visible

The light source is only at the very bottom of the display, and just isn't strong enough to do a good job of making the display readable at night, or more readable in the day.

The display is nearly unreadable in the dark unless you grab it with your hand and hold it right in front of your face.

it has fun extra not mentioned in title of moon phase graphically displayed.

The display is easy to see, and when you press the snooze button on top it backlights the display for night time viewing
