Sent musical clock to have sensor replaced. Clock is in fine condition and works well except that it doesn't play music on the hour. It does play if you press the demo button. Coserv claims the clock cannot be fixed and I have to pay $325.35 for replacement (this is more than I paid for the clock). Hard to believe they are still selling these clocks and the sensor cannot be replaced. The clock is only 2-3 years old.
