Review on Hushtong 2 Pack Refrigerator Thermometer - Large Dial Refrig Thermometer: Accurate Temperature Monitoring for Your Fridge by Divya Flood

I bought this item to control the temperature in the fridge and freezer. I tested their accuracy by placing them next to 3 other thermometers that I have tested closely and they were 5 degrees lower on one and 4 degrees higher on the other. I am a retired engineer who once tested aerospace products at the National Bureau of Standards. I put them in my cart because I don't want to go to the Amazon store to return them during the COVID-19 troubles.
