Review on 🌡️ CAMWAY Waterproof Digital Refrigerator Fridge Thermometer with Max/Min Record Function and Large LCD Display -4°F to 122°F - 4Pack with Bonus Screwdriver Set by David Burrell

Used them in 2 fridges and 2 freezers to see if they were out of temp zones. Out of the box, they had different timings, allowing them to adapt in different zones. Not that accurate, with a 4 degree difference on one of them and a problem with two digital displays. Fixed one by clicking. There is no way to adjust the tempo. Worked well to check the min and max freeze defrost cycle temperatures to see the difference in degrees. Displays freeze in the freezer but just need to be wiped down. Other ways are easy to read. Hook stands and magnets feel comfortable. Paid $17 for 4 of these and good to get an overview of the temps.
