Product review (2 stars): You get what you pay for.
Expected better.  The batteries were dead when I first opened the package.  So I spent more $ in batteries than on the thermometer itself.  Two of the horizontal lines do not work in the humidity section of the display.  Finally, there is no way to force it to display temperature in Fahrenheit, only Celsius.  The only reason I gave 2 stars is because it works and seems to be fairly accurate.
