Query: Worked fine for 9 months - then died

I used this timer for 9 months and was very happy with it. Then, upon returning from a vacation, found that it hadn't been working while I was gone. The display was messed up and I couldn't get it operating again for more than a day. I need a timer that I can rely on when traveling. This one is going in the trash.
