Query: Works well, but without colored backlight can't see numbers

As the title says, it works well. It came on time and as described in an original box.Pros: Bright light, on time clock, long cord, adequately loud alarm, battery powered so will keep time even if power goes offCons: Won't work without battery, the button is a little weird, basically you have to slide it over to turn the alarm on/off or set the time or alarm. You can't turn the alarm off till you open the top, it has a weird viewing angle, don't put it above your face cuz you won't be able to read it. If you turn off the colors there's no clock, its just black. The colors are pretty bright so I can't have the clock pointing toward me at night
