Review on Keep Your Food Fresh With AEVETE Refrigerator Thermometer - Digital Fridge Freezer Temperature Gauge - Magnetic Back - Large LCD - Easy To Read - Pack Of 4 - Black by Griselda Monclova

Put one in each part of your refrigerator. The Min/Max display will let you know if either compartment got too warm. If you leave for vacation and the power goes out, you could have bad food and not know it if the power is back on when you get home. The thermometer will let you know the min temperature since the last time you reset it.I like moving it around in my refrigerator to see what the different temps are throughout. In the back bottom, it is right at 34, the door 39. I knew it was colder in the back bottom because some food would be near frozen. This is an easy way to confirm it.
