Review on 🌡️ White Digital Refrigerator Thermometer with Large LCD Display, Waterproof Fridge Freezer Room Temperature Monitor, Max/Min Record Function, Magnetic Back - Ideal for Kitchen and Home by Julie Johnson

Well 2 out of 3 thermometers work. The third turns on, but with an error. It's not the battery as it shows numbers, but it's either an internal fault or it just won't light up every now and then. These are not quality items judging by their feel and appearance. Temperature accuracy appears to be correct to within 2 working units. There is a small plastic hook that can be used to attach to the fridge shelf but it doesn't fit mine. There are two small magnets on the back that allow you to attach it to the metal parts of the interior. I think I'd be better off with the traditional type of thermometer I used in my RV fridge, which simply reads the temperature on a numbered red mercury gauge. At some point I won't have to deal with batteries anymore.
