Review on Portable 360°Rotation Temperature Display: Stay Informed Anywhere by Warrick Batebi

Works great. In reviews that complain about temperatures in Celsius, this fan actually toggles between Celsius and Fahrenheit. Of course, there's no setting to only show one or the other, but you get both. My only complaint is that the instructions in the manual for setting the watch are inaccurate. It took me a minute to figure out what the Install button actually does, but it should be easy once you get the hang of it. The instructions say to hold the button down until "the hands of the watch start to rotate". Well, there are no "hour hands" on this item. By holding the button, you can only move to the next item to set (e.g. move from hours to minutes). To change the value, you must press once quickly to increase the current flashing value.
