Review on 🌡️ Waterproof Digital Refrigerator Thermometer - Large LCD Display, Max/Min Record - Ideal for Fridge, Freezer, and Room by Ivrington Miller

Although this is close to value for money, low accuracy and accuracy are too large. You can see the difference between the two thermometers is almost 3 degrees. Anything over 1 or 1.5 degrees Fahrenheit is too much for me. Not the right temperature either, which is around 72.9 degrees. Perhaps you could use this if you are calibrating yourself - you would need to have a thermometer that you trust and compare it across multiple temperature ranges. You can't trust him yourself.
