La Crosse Technology WT-5360U Atomic Projection Alarm Clock Review

Not surprisingly, I chose this clock for 3 reasons: it sets itself, it projects the time on the ceiling/wall, and it's quite inexpensive. After a needlessly painful setup (more on that later) it set its own time, and the time projected on the ceiling is easy to read with my glasses on (just barely readable w/o glasses).
The first problem I encountered was plugging the power supply into the clock. It uses a standard coaxial DC power connector that plugs into a socket on the bottom of the clock. Unfortunately, the hole through which you access the socket is not only much larger than the socket, but so much larger than the socket housing (a box containing the socket connector) that unless you have sharp eyes and carefully align the plug with the socket, the plug will slip into the gap between the socket housing and the hole in the clock case.
After getting the power connected, I left for work, and when I returned, the clock showed the correct time--only off by 3 hours. OK, so I needed to set the time zone. There are no buttons labeled "time zone", "TZ" or anything similar. A quick check of the manual (don't lose that manual!) revealed an unintuitive process for setting the time zone (typical of devices that don't have enough buttons):
1. Hold down the "Mode" button for 3 seconds. The currently selected time zone will be displayed.
2. Click the "Mode" button until your time zone appears.
3. Click the "Snooze" button.
Despite its poor design features, this clock basically works as advertised and is inexpensive. Since most of the time, you won't need to touch it, if you can read relatively dim, red 3" numbers on your ceiling, then it's probably a good choice. Just don't lose the manual!

No more patting around for the glasses to check the time after than early morning alarm. This projection clock beams huge digits, visible to the blurriest of eyes, on walls, ceilings and other smooth surfaces. Every time it's plugged in or turned on, the clock sets itself for precision time by receiving radio signals from the official US Atomic Clock. That means it also shifts automatically to and from Daylight Savings Time, so there's no more showing up to work an hour late or early twice a year. The unit also reports indoor temperatures and features an LED backlight for easy readouts without using the projection feature. The projection arm rotates for proper viewing at any angle-without rolling over. Open the eyes. Read the time. Close the eyes. An automatic focus mechanism presents clear readouts on any smooth surface. And, a perpetual calendar helps you stay on schedule. Hang it on the wall or set it up on a desk with the detachable stand. AC power adapter included.

The clock works just fine. It reset itself for daylight savings time. The time and day are easy to read. It is just what we wanted.

Sangean RCR-2 Digital Atomic Clock Radio with Dual Alarms Review

I spent a lot of time trying to find the perfect alarm clock for my bedroom and, as you can tell, I am still looking. The Sangean RCR-2 certainly has some attractive features like the atomic clock, which took a few hours to set itself, and the nice styling but it fails in so many areas as an alarm clock. First, and most importantly, the display is unreadable. It is very busy with lots of symbols and numbers but using very thin LCD numerals for the time and the off axis viewing angle is very small; you must basically face it head on. Worst of all, however, is the blindingly bright orange backlight with makes is impossible for night adjusted eyes to read the display if you want to check the time in the middle of the night. It is so bright as to cast shadows throughout the room. I keep it across the room but I can't imagine trying to sleep with this minor sun positioned on the nightstand. Sure, you can turn off the backlight but then the clock is invisible at night. Maybe LEDs are not cool but they make a lot more sense for an alarm clock. Also, it takes at least four button presses to turn on the alarm as opposed to one on my old alarm.

This modern clock radio is a step above the clock radios of the past. For starters, the radio updates its time automatically from the U.S. atomic clock in Boulder, Colorado. While this may force you to work or school on time, the benefits of a constantly updated timepiece are critical in this fast-paced world. The radio even adjusts itself automatically for daylight saving time. The illuminated LCD screen gives you vital information, including: time, date, day of week, sleep, wake times, naptime, and radio information. With the gentle wake option, you can choose for the radio's volume to start low and slowly build over time. The AM/FM radio has fourteen presets for individual programming. The clock radio also features an automatic preset system which scans and memorizes available radio stations. With the two alarms you can set wake-up times on the same or different days of the week. The sleep timer is a nice feature for those who use the radio as a sleep aid. There is a headphone jack for people who want to listen to the radio without bugging the person besides them. The clock radio's color is silver and its styling is modern and sleek.
