Keep the Westclox Nap Mate in a bag or purse and doze off anywhere without fear of sleeping through an important meeting or class. Measuring 5 by 4-1/2 by 3-3/4 inches when open, its just the right size for stashing in an office drawer for the occasional afternoon siesta. In addition, it also makes a great travel alarm or bedside clock. The face features an easy-to-read LCD lighted display, with quick access to the Snooze/Light button as well as other settings. Best of all, the nap feature lets you program the alarm in 15-minute increments with the simple press of a button. The sleek case folds flat to fit neatly in a suitcase, then folds out to make its own stand. The Nap Mate runs on a single AA battery included with purchase. --Mary Park
