after spend quite a long time shopping on-line and in the store -lrb- I return two travel clock after get they home -rrb- , I purchase this travel clock . it be very inexpensive , extremely easy to use -lrb- no manual necessary -rrb- , and work very well . the alarm be neither too loud nor too soft , it do not collapse when open -lrb- like two other travel alarm I purchase -rrb- , it be make of lightweight plastic -lrb- reasonably durable -- very sturdy compare to some three time the price -rrb- , have a unlimited 4-minute snooze feature , and light up when the snooze button be depress . it would have be nice if the number stay light at night and the lighting feature be extremely dim , at best . nevertheless , it be very lightweight and measure only 3-1\/2 '' x 2-1\/2 '' x 1\/2 '' -- can fit anywhere , even in a pocket . the only other possible downside be that it use a 1.5 v button battery instead of a standard aa or aaa . nevertheless , I like it enough to use it at night in place of the abrasively loud alarm clock I previously use , which my kid have nightmare about .
