## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well! Bought another one!
*by J***D on January 1, 2026*

Accurate and easy to use when checking RV refrigerator and ice chest temperatures. A little slow reaching new temperatures but a great peace of mind.

### ⭐⭐⭐⭐⭐ GREAT THERMOMETER
*by C***T on December 17, 2025*

IT DOES A GREAT JOB WITH MY CHEST FREEZER. I KNOW THAT IT IS WORKING BY JUST LOOKING AT THE THERMOMETER.

### ⭐⭐⭐⭐⭐ Peace of mind
*by "***" on December 26, 2025*

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.
