I'm old and cranky - I need a good snooze button! I like to sleep in near complete darkness, so at first, the red glow of the numbers on my ceiling made me aware of an ominous glow above me - but just like the moon and stars, you kinda adapt to the subtle ambient lighting. In the dead of night, as I roll over in bed, I can look up at my ceiling to see the time without waking all the way or assaulting my eyes.
When the alarm goes off, it a simple beep - not beeps - one single beep that is loud enough to wake you, but not so loud it startles you. It will be followed by other single solitary beeps about 3-4 seconds apart. I can always slap the snooze button before the second beep comes along. The snooze is just the right time interval for me - 8 minutes. I can actually get another few minutes of true sleep before waking fully.
If the alarm goes off when it is still dark outside and it's dark in your room, the glowing blue of the clock might startle you - as it is bright. Plugged in, the red numbers are available at all times. When running solely on the 9v battery, the red light is only available when pressing the snooze bar to illuminate the time - on the face.Read more ›
*** When I was looking for an alarm clock, I knew that two features were must-haves on my list:
1. Auto synchronization via the atomic cock signal.
2. Ceiling projection.
---Auto synchronization via the atomic cock signal.
I already have a watch that synchs to the atomic clock, and I love this feature. Eventually all clocks in my house (and on my person) will be auto synch (either via atomic clock or cell phone carrier). In my opinion it is the only way to go if you want to be assured of accurate time keeping.
Note that some alarm clocks are advertised as "Automatic Time Set" (for example Sony ICF-C218 Automatic Time Set Clock Radio (Black)), but these do not automatically synchronize their time setting. They call themselves "Automatic Time Set" but all this means is that they come pre-set from the factory with the correct time and have a daylight saving auto-adjustment.
--- Ceiling projection.
I had never had a ceiling projection clock before. I was concerned that the projections would be too bright and would interfere with my sleep. This fear was unfounded. The projection of this clock is easily read in a darkened room, yet does not give off appreciable light itself. The projection is red, and looks much like an LED display.
Unfortunately and predictably, in a fully lit room you will not see the projections.Read more ›
