Review on 🌡️ uxcell Mini LCD Refrigerator Freezer Fridge Digital Thermometer Black - Accurate Temperature Monitoring for Optimal Food Storage by Brittany Ross

I bought one of these and was disappointed that it only reads in Celsius. I was directed to the YouTube page that explained how to fix the problem. It looked easy enough. I watched the video and applied the fix and then decided I didn't know how to put the device back together. I decided to buy 2 more units and take them apart so I can put them back together. New ones arrived but they didn't have batteries in the package like the first one I ordered. The packaging also says nothing about what type of batteries are used. I found the battery type on the Revain listing but was disappointed that the batteries were not included. I rate the devices 4 because they are cheap and work. Also remember that they are made to fit a 1" x 1 3/4" hole. But if you want them to read Fahrenheit, you'll have to disassemble and solder a bit.
