Review on 🌡️ AMIR Refrigerator Thermometer with High/Low Temperature Alarm - Enhancing Efficiency and Food Safety by Jon Louis

I bought this because my freezer was unplugged and about 40 pounds of groceries were ruined. The device itself works, the temperature seems accurate and there is an alarm if the user set temperature is exceeded. BUT the alarm clock is not very loud and turns itself off after a few minutes if not reset. I could see it being useful for a regular fridge/freezer in the part of the house where people would be, but that's about it.
