This review is from: Hama Xavax Fridge/ Freezer Thermometer (Kitchen & Home)
If you can freeze stuff sufficiently at -18 degrees celcius, then why waste energy by putting your freezer on max when you can have it on setting 3? This thermometer helps you do that. I have one for my fridge too; this help me understand which parts of my fridge are colder than other e.g. the door is roughly 8 degrees C and the bottom tray is about 2 degrees C. This helps with defrosting stuff.
