Review on 🌡️ 2 Pack Refrigerator Thermometer - Wireless Digital Fridge Freezer Room Temperature Monitor (-20 to 60 Degree) with Large LCD Display, Min/Max Record, Magnetic Hook for Indoor Outdoor - From -4 to 140 F by Cole Dutta

So if you go on holiday and the power goes out on a Tuesday, the device will automatically reset after 24 hours. For example, until Wednesday when it resets, it will show 68° as the maximum. You come back on a Saturday and the device only shows the high/low of the previous day. It's just dangerous and not stated in the product description. The point is the last line of a poorly written statement that no one ever reads. Wow. You could accidentally feed your family thawed and refrozen food while thinking the fridge is working properly. DO NOT BUY THIS!
