Works great in our camper refrigerator
Beth C—July 17, 2025✓ Verified purchase
Purchased to keep track of temps in our camper refrigerator - easy to put above refrigerator to enable us to check the temps without continually opening the door to check. Seems accurate, quality is good, bright enough to see easily and very pleased. Read more

No "Off" Button!
David—March 1, 2025✓ Verified purchase
There’s no Off button! How do you turn this off? It runs on battery, and I don’t need it on 24/7 In fairness to this product and the company I needed to upgrade this review from a 1-Star to a 4-Star. Here's why: I use this thermometer to gauge water temperature while thawing food for my snake. It only gets used once a month. Since I bought this product it has worked as expected and accurately. Yes, it's always on and on my kitchen counter by the sink. The bottom line is that it works—it works exactly as described. The batteries are still the original, so they last a long time. I find myself looking at this thermometer while in the kitchen to get the room temperature. I upgraded it to a 4-Star because it works, but I lowered it from five because it would be a full 5-Star if it had an on/off switch like my other top-brand digital thermometers. Read more

Peace of mind
"abcs38"—December 26, 2025✓ Verified purchase
Love this as used for registering my crawl space temp. It gives me peace of mind when the temp drops as I know without a doubt if the water pipes are in danger of bursting. There is no off switch so the battery has to be replaced/removed after every use but shows large digit numbers in Centigrade or Fahrenheit. Read more

Very good general purpose thermometer for our RV refrigerator. Easily readable and reliable.
Whiteivory—May 31, 2025✓ Verified purchase
We are using this with our RV refrigerator when out. The thermocouple probe/sensor and wire slip right between the door gaskets and gives us a good idea of the internal temp. Its demonstrated good battery life and is easily readable...a good design. Well built, it continues to perform well. Read more

Good for the money
Coffee Tim—January 24, 2026✓ Verified purchase
Arrived earlie than promised. Put the battery in and it immediately started working. Compared it with other digital thermometers and the reading was within limits. So far so good. Will have to wait a while to see if it holds up. Read more
