I have have 3 of these clock over the past 15 year . my 2nd one just die after several hard year of use ... travel literally around the world multiple time . be sooo happy to find a new one on Amazon . this clock be the perfect size -lrb- smaller than a business card -rrb- , it light up with the press of the big `` light '' button , and it be easy to change the time & alarm . and it do not make unwanted beeping noise every time you want to press a button . they have be very durable and ... best of all ... it slide very easily into a briefcase or shave kit bag . it be perfect for the business traveler !
