Frienda 4 Pcs Black Fridge Thermometer Refrigerator, Button

Works

Do not let these get submerged in water for any length of time. The water does get in them. We tried to use them in a cooler with ice. When the ice melted and they got into the water, 2 of them were not usable anymore. Otherwise, they work great in a fridge or freezer. Accurate.

These are great!

Work great but keep switching back to Celsius. And the hooks that are attached to it fall off pretty easily.

Excelente, como se describe, todos funcionando bien

Item as described except description excludes how short the battery life is. These inexpensive thermometers don't agree (lack of precision), but that was expected. Relatively short battery life means that the initial relative low cost is overcome by the need to replace batteries relatively frequently. Otherwise, thermometers functioned okay (except one that did) while the batteries lasted. They do not meet my need for an inexpensive thermometer.

They are being used in our farrowing rooms to monitor night time temperatures and and they work great showing the highs and lows. Can easily change a battery when needed and the batteries can be purchased as well (2036 I think)

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.
