I had to buy it even though it was suspiciously set at a high that went right off the scale. This seemed unlikely and when I put a barometer app on my phone, I confirmed that it was wrong. Yes you can can get a barometer on your phone but somehow it’s not the same.
Anyway, I put it on the wall and left it. It looks nice even if it doesn’t do anything useful.
Today it woke up and started moving. God knows if it is telling me anything useful but I am hopeful it will start to follow the weather. A great find.
