Review on 🌡️ AcuRite 00986M: Digital Wireless Fridge and Freezer Thermometer with Alarm and Max/Min Temperature for Home and Restaurants - Keeps Food Fresh! by Catherine Schwarzer

[UPDATE 09/18/2018: About 34 days after purchase, fridge sensor #1 stopped working. It remains fixed on the last number displayed or reports nothing at all. I reset the display unit and removed the batteries from all 3 units, then put the batteries in the display, then sensor #1, then sensor #2. Currently only freeze sensor #2 is working. I am using Energizer Ultimate Lithium AA batteries with freeze protection. My rating has dropped from 4 to 2 stars. This is a good product when it works. I'm disappointed that my purchase went through the Revain return window, but I was able to contact Revain support to accept the return as a one-time exception.] Like most here, I bought this to keep my fridge temp warm control and freezer. My $2,300 Kenmore was warmer than usual, and even after Sears found nothing wrong, I suspected the food wasn't cooling properly. The ice on the freezer side was soft and the milk on the fresh side wasn't as cold as it used to be. This device confirmed my suspicions. The fridge was about 46F and the freezer was about 20F. It had to be operated at or below 40F, or at or below 0F. The display is attached to the fridge with magnets (a certain distance from the monitors must be maintained) and the monitors can be attached either with a clip or with a suction cup. in the fridge/freezer. Monitor 1 defaults to Freezer and Monitor 2 to Refrigerator. You can change this yourself, but the default setting is programmed to beep at certain temperatures. Alkaline or NiMH batteries should not be used in the freezer as they will not work below -4F. Instead, the manual recommends purchasing lithium batteries. I bought some from Energizer and it worked fine. I went ahead and used the same battery for the fridge section. It's nice to see the highs and lows for each section, and the alarm function is a nice feature that should warn you before the food goes bad.
