Review on ORIA Digital Refrigerator Thermometer - Waterproof LCD Display, Max/Min Record - 2 Pack, Ideal for Kitchen, Home, Restaurants, Bars by Donald Marin

Bought 2 packs to control the actual fridge and freezer temperature in my new fridge. A test run with both devices in the cold store showed two different temperature values when the devices were placed next to each other. Same result if both devices were in the freezer. The difference was from 6-8 degrees. Left one unit in the freezer overnight and found it wouldn't turn on until thawed a bit. What's so good about that? Either way I will use one and keep one as a spare but I do not recommend this thermometer to anyone.
