I have three of these around the house, bedroom, garage/workout area, and bathroom. The one in the bathroom started being wildly inaccurate after a period of time, and changing the battery helped, for a few days, then it was off by large and random amounts. Clocks are a reference item, and need to stay more or less accurate over time, until they are just plain out of battery power. The bathroom clock did not succeed. The two in the bedroom and garage/workout area worked fine and were pretty accurate.
Since I accidentally smashed the working clock in the garage with some lumber, I will buy two more of these to replace the garage/workout area, and to hope that the new one in the bathroom lasts longer this time. It looks great, easy to read, and is pretty cheap, so we'll see. I'll be watching the bathroom carefully to see you long it lasts (or doesn't), so I can characterize it's longevity. Maybe I need to pay more for a more moisture-proof, humidity-proof clock. Not sure how to do that. Hopefully, these new ones will work and the problem will be solved.
