CDN Audio Visual Freezer Alarm Review

Auto-defrost refrigerators/freezers cycle their temperature between 0 degrees F and above 25 degrees F.Unfortunately, this alarm doesn't accomodate the cycle resulting in false alarms.The owners manual offers a cop-out solution, "wrap the sensor in foam". OK --so how does one calibrate the sensor and know that it is set properly? It would take a lot of trial an error, adding foam, removing foam . . . who has time for that? It needs a switch where the consumer can pick the alarm temperature.
