Refrigerator Thermometer Digital - Fridge and Freezer Alarm Alert When Temperatures Drop - Ideal Fridge Freezer Thermometer with Alarm and Max Min

Product works well - alarm is too quiet. Set up, could be better. Looking back I wish it was on 2 AA batteries and a louder alarm. But it fits my needs to prevent or address a freezing condition on a water tank.

Most of the negative reviews are related to the challenge of setting the alarms on this tiny little device. My own confusion originally led me to rate it poorly however once you know how to program the unit, it's actually pretty useful. First of all, press and hold the alarm button. It will show you the current maximum temperature that it will accept. Which is approximately 39 degrees Fahrenheit and probably fine for the fridge. If you want to change that temperature hold the button on the back of the unit. The temperature will increase and eventually it will scroll all the way around to start at the lowest acceptable temperature. Now push the alarm button again and you will be setting the lowest tolerable temperature. If you push and release the alarm button it will toggle between being on and off. This is useful because when you use your refrigerator or freezer often the temperature will increase above your set point. After six years our refrigerator has been acting up, so this little cheap unit can be a lifesaver for the food in my refrigerator

This product works, BUT, the settings and names that they use are very hard to understand. For example, they call the temperature probe that will be placed in your fridge/freezer as OUT. The external display is called IN. So strange to name them that way. Another odd one is the way you have to set the min/max temperatures. It takes some playing around with and KEEP THOSE INSTRUCTIONS! But at the end of the day this device does work so I’m giving it 4 stars, the deduction is purely for the interface/settings.I will update this review if the unit ever fails.

This thermometer is easy enough to set up, but it's not intuitive. Don't lose the instructions! As far as operation, I don't think it actually works. I am using it to monitor the temperature on my heated sun porch where I keep my plants. I want to know if something happens and my heater stops working. I check it several times a day and find that it always says the temperature on the sun porch is 57.4 degrees, and the temperature inside is 63. 5 degrees. Meanwhile, my old fashioned thermometers on the sun porch range between 60 degrees at night and 75 or 80 degrees in the daytime, and my indoor temperature fluctuates depending on a variety of factors. I don't know if this thermometer will let me know if the temperature on the sun porch drops below 50 because it doesn't seem to know.2-13-2021 The temperature did drop to 50 a couple of hours ago and the alarm sounded several times loudly enough to hear. :)2-16-2021 Today was a bright, sunshiny day, so I was surprised to hear the alarm go off in the middle of the afternoon. I checked the temp on the indoor gauge, and it said the temp on the sun porch was 49F. I stepped onto the sun porch and found that the actual temp was a little over 90F. Now (several hours later) the actual temp is 65F, but the gauge still registers 49F; however, it is not sounding the alarm, which is set to go off at 50F.

Accurate and works well. I use it on my freezer in case the door does not shut completely. I like the alarm is not constant or too loud. Loud enough that I can hear it in the kitchen thru the closed door to the basement where the freezer is, but not load enough to make me want to run down to turn it off. Also it's a series of four beeps. It does three sets of those and then stays silent for about a minute before starting again. Currently I just have the cord running past the gasket on the hinge side of the door but the probe is small enough to fit thru a 1/4 inch hole, so At some point I will drill a hole to run it thru the actual door and seal it with some silicone.

These are VERY not user friendly. I consider myself quite adept at setting up electronic devices. These are very difficult to set up. The instructions are written extremely poorly. You javelin to remove the batteries in order to reset a temp that you have set incorrectly. Not something I would buy again. Going to find something else.

I bought one of these in late 2020 to monitor the temperature in a chest type freezer. After a but more than three years it is still working with the battery that came in the package. I would buy this product again.

This item was very easy to set up and install. I had no problem at all configuring. Instructions, though not perfect, were still easy to follow.This really makes me feel better about my food in a 30+ year old freezer. The alarm is set to go off if the freezer gets too warm. I have it set so it will alarm when the temperature is still below freezing, so I don't have to worry about food thawing before I am aware of the issue. Every now and again, the alarm goes off when I have the door open for a while, but that just assures me the alarm is working.
