Review on ETHMEAS Digital Refrigerator Thermometer Function by Theresa Jones

Excellent device. In most cases it is easy to route the sensor cable through the sliding glass window. The instructions don't say exactly how to set the high/low temp. When setting, press the warning button, hold it for 3 seconds, and you will see the reading. You have to hold until the desired temperature is reached, the reading will only get higher, so you have to wait for it to go above about 110 degrees and go back down to about minus 5 degrees and continue until the desired temperature. It has good battery saving function. , it only updates the displayed temperature every 25 seconds. For less than $15, this is the best device out there.
