With Some Clocks, Rude Awakenings

The good: Where to begin? It's compact, lightweight, simple to set up and super-slim in size. The built-in cover that folds over and doubles as a stand with non-slip feet is especially nice, as is the snooze function and backlight activated by a gentle tap on the clock face. It comes in a variety of colors including ruby and sapphire, and two AAA batteries are included. Believe it or not, we could go on.

The bad: Occasionally the bright backlight didn't turn off after eight seconds like it's supposed to (a minor detail; this travel clock is nifty.)

Grade: A

· Sonic Shaker Portable Vibrating Travel Alarm Clock from Sonic Alert

($29.95, http://www.sonicalert.com)

Weight: 5.8 ounces with batteries.

Special features: Four-minute snooze function, crescendo alarm and backlight. Pillow clasp and travel case included.

The good: Compact, easy to set, easy to read, lightweight and several alarm options (buzzer, vibrator, buzzer and vibrator). The gentle yet effective vibrating that "shakes" you awake is clever. While particularly good for the elderly, those hard of hearing or considerate folks who don't want to disturb other sleepers, we think it's an excellent choice for just about anyone. Two AA and one AAA battery included.

The bad: The 90-decibel "extra-loud" alarm didn't sound all that extra-loud.

Grade: B+
