Negative I find that the temperature range extends only to -20 degrees Celsius. That's in many locations in southern Germany falls below the winter often times, and you might just know then quite like how cold it has become really. However, I knew it before, because it is correct in the item description.
For my purposes, it does the thing, but for the price you could have done it better. After all, it looks quite appealing and the temperature display is a good size and therefore easy to see even from a distance.
