Mini Thermometer, Digital Refrigerator Freezer Thermometer with LCD Display - 6 Pack Fahrenheit (℉) Thermometer Hygrometer for Humidors, Greenhouse, Garden, Cellar, Fridge, Closet

These come in a pack of 6 and each one displayed a different reading. They were all within 2 to 3 degrees of one another but none the less all different. The temperature reading is very tine and the humidity reading is more than half the screen. I didn't care for them but that is just my opinion. Now someone else may have another need for them and find them to work just perfect. But for measuring the temperature in a fridge or freezer these are not the ones for that.

Arrived with 2 of the four having dead batteries but 2 new batteries were also included so switched out and all works good now.

O’Tay… just KIDDING about the TOASTER thing!These little gizmos are spot-on. Consistent and uniform (see pic) with regard to relative humidity.As such this was my SECOND order and I am comfortable to post a review.If relative humidity (RH) is of interest to you I DO recommend these little guys for and in your efforts.

I was in industrial instrumentation technician for 25 years and I bought other thermometers that have .54 degrees Fahrenheit accuracy. Most of these were .2 degrees the same temperature as the other ones. I have bought two orders of 12 thermometers because I like these very much. They are a good value and work very well. Only thing that would be better if the temperature was the large number and the humidity was the small number. I have 3 portable coolers and a bunch of fans that I am keeping my house cool with and monitoring the temperatures and humidity at the windows, on several fans and in different rooms.

Buyers need to know that the tempature is in small print. The large number is humidaty.

I was having trouble with the cooling system in our house, and wanted to know the room temperature in many rooms, as well as the temperature coming out of the ducts. Just wish there were a way to reverse the display to make temperature large, and the humidity small. They are not very resillient, when dropped from 8 feet to a wood floor, the humidity sensing on one quit. In general, though, they served the purpose

Far better than I expected for the price. All indicated the same temperature within on degree F and humidity within 10%. They have yet to fail after being used in a laboratory environment since arriving.

These are great, I bought 24 and put them all over the house. It makes it so much easier to monitor comfort levels and adjust the heating system. We have single pipe steam and these were a critical tool in balancing the system. Also, I keep one on my wife’s nightstand. When she gets into bed and says she’s cold, I can use it to assess whether the heating system needs to be turned up or whether I just need to give her a hug!You will be surprised how nice it is to have “situational awareness” of the temperature and humidity throughout your home. I particularly like knowing the humidity. When it gets in the teens I pull one of the steam vents and let steam pour into the room... instant humidity and comfort!
