Doesn't do anything. When the timer gets to zero, no sound. When the alarm time passes, no sound. No animation, nothing. It will let me set up as many alarms and timers as I like but none of them make any sound. All the of the alarm options play for me when selecting the sounds, but when the timer/alarm is up, nothing happens.

Only worked the first time...

It worked for a while, and then just stopped. Disappointing, since I was starting to count on the alarm to go off....
