Frienda 12 Pcs White Digital Fridge Thermometer Waterproof Refrigerator and Freezer Max/min Record Function LCD Screen Refrigerator Thermometer with Hook and Magnetic Back for Home (Button)

So far all seems to be working well. Accurate reading and easy to read.

These work and seems to keep ok temperature, at least enough for my curiosity's sake. My complaint is that every so often they default back to Celsius and I have to tap the temp button to get them back to Fahrenheit. But, next time i check it, it's on Celsius.

Excelente, como se describe, todos funcionando bien

The battery is fine, but the units themselves have a very short lifespan.

Buyer beware. Multiple units of this product will fail when put to freezing temps. They will turn back on at room temperature. If you need this to monitor units around 0 degrees F, this is not the product you want to buy.

They work as advertised.

The display is very dim on all of them (12pk). A couple of them randomly change back to celsius periodically after having them set for farhenheit. I don't know why they do that since I don't have them placed anywhere they could have the button even touched! I guess because they were so cheap! They do seem accurate on the temperature though.

Super easy to use and the health inspector loved it.
