Product review (5 stars): February 2nd, 2017-bought version worked fine. Great value for the money. Fahrenheit display conversion pictured here.
2017.02.27 was when I bought this item, as "Mini LCD Refrigerator Freezer Fridge Digital Thermometer with Remote Temp Sensor - Black (by
LuckyStone), sold by: NiuBile." Now it is listed as "Kingzer Digital LCD Thermometer Temperature Sensor for Refrigerator Freezer (by uxcell)." I learned to look for the correct contact to solder by reading other reviews here, some of which mentioned evolving design which made it harder to tell what to do. Maybe I was sold old stock, but I'm posting the photo to clarify what was available on what date. The "After" photo's soldering point looks a little weird because I don't have a very tiny soldering iron, and it left a pointy peak of solder no matter what, so I clipped the excess solder off after it cooled.
