I find the alarm on this clock work very well and be easy to set up . however , with the first clock I receive , you could not see the time at night because the background do not light up enough . I call the company and they replace the clock , which I appreciate , however , the second clock do not work any better ! you have to turn on a light to see what time it be at night time which defeat the purpose of get a clock that be suppose to light up !
