Review on 🌡️ Wireless Refrigerator Thermometer Set - Indoor Outdoor Digital Temperature Monitor, 2 Remote Sensor Gauges with Audible Alarm, Min/Max Record for Home Fridge Freezer (Battery not Included) by Doug Taylor

We had a problem with our fridge, it just started not cooling properly. It showed the target at the door, but we had to constantly lower it so that it "felt" the cold. In the end, when some food was spoiled long before spoiling, we took the thermometer and put it in the fridge. Where he reported it was much higher. Now it is located on the side of the refrigerator and controls the cold zone and the freezer compartment. Accurate enough, works through the fridge and just inserts the sensors. Would buy again.
