The clock is in an open faced box, no cellophane or plastic. The clock is held in the box by a tiny Phillips screw through a plastic disc, the back of the box and into the back of the clock. One positive fact is that you don't need to find a screwdriver. The disc has two raised pieces, so it can be unscrewed by hand like a wingnut.
It comes with good instructions, but ignore the generic battery warning (i.e. don't mix old and new batteries, don't mix battery types - alkaline, standard or rechargeable) because it only takes ONE AA battery.
The instructions mention and on demand back light. The light appears to be an LED next to the #10 on the face of the clock, not a back light. The light is turned on by pressing and holding the snooze button. The light is sufficient to light the face of the clock in a dark room.
The clock is only 3 inches tall, so I would be reluctant to try the light in a dark room. More apt to end up with the clock on the floor.
The time and alarm adjustment knobs are in an oval depression on the back. The knob for setting the time is easy to use. The side of the depression by the alarm set knob sticks out farther than next to the time time knob making it hard to adjust the alarm. I could only manage to adjust the alarm 30 minutes at a time.
The alarm speaker is a small spot on the back of the clock. When the alarm goes off it has a pulsing chirp for about 7 seconds before switching to a constant louder chirp.
With the clock 2 feet away, I could barely hear the first alarm and even the constant alarm didn't seem that loud. I hit the snooze button to silence the alarm and turned the clock around backwards. When the alarm went off the second time I could hear it.
I set the alarm the first night and slept through the alarm the next morning.
The second night I set the alarm and turned the clock around backwards and it woke me up with the constant louder alarm.
I would be afraid to depend on the alarm if I really needed to get up for some reason. I'll only use the alarm if I'm already up and with the clock turned backwards to remind me that I need to leave for an appointment.
It keeps good time for a battery operated clock. Over a period of two weeks, it gained two seconds each week.
