Review on 🌡️ Waterproof Digital Refrigerator Thermometer - 4 Pack, High Precision Freezer Room Thermometer with Hook for Kitchen Home, Convertible °C/°F by Andrea Jackson

I ordered these to find out what my fridges were capable of. They helped me get through it, but it was a short-term relationship. The accuracy is questionable, with one I found that reality is 3 degrees steeper. They worked perfectly, and suddenly within the same week two stopped turning up when in refrigerators. If I take them out and reheat them, they reset to Celsius. When I put them back in the fridge at Fahrenheit, they again stopped working when they got cold. They don't fit in the freezer, they're just fridges at around 36°. I don't know if the batteries are dead. But I've only had them for 2 months.
