Initially I had trouble changing the temperature display from Celsius to Fahrenheit. The thermometer comes without documentation, but the package states that it shows temperature in both Celsius and Fahrenheit so I knew there was a way. The back of the thermometer has one button, however pressing it did not change the temperature display. Eventually, I decided not to just press, but press and hold counting to 10 and then then the temperature display changed to Fahrenheit!
I like the mounting system of this thermometer. The back of the unit is magnetic and so you can mount it directly to something metal. If you need to mount it on something that is not metal, then you can use the disk that is included in the package. The disk has sticky tape on one side and metal plate on the other. So you can create a match of metal anywhere you want to post this thermometer.
Overall, I am quite pleased with it. It is small, it has a nice clear display, and it is accurate.
