Check out this video on Amazon.com based hygrometer provides a clear display with precise measurement values (compared with two other hygrometers) and provides in addition to the maximum and minimum values since the last reset even a "Smiley" indicator, which indicates whether a Humidity in the "comfort zone" is (40-60%). I think this is more for frills, because if you feel good, everyone should decide for themselves ... but otherwise just a good price for a good device - especially me a large and clear display.
