Mine has been running since October 2017. I reset for daylight- standard time, otherwise it stays within a minute.

I wanted to wait a week or two to review the clock to make sure it kept working. My luck was much better that the previous reviews. Clock arrived quickly and well packaged. Change out of my old quartz clock was straight forward and replacement took about 20 minutes. So far I’m very pleased!
