NeKan Digital Refrigerator Thermometer Freezer Thermometer with Min/Max Display Wireless Indoor/Outdoor with Audible Alarm (Battery not Included)

I set these up with brand new batteries and one was not reading correctly. I had them right next to each other and it stayed at 75 degrees while the other one dropped as the afternoon went on. So I thought perhaps it was the batteries. I put two more brand new batteries from another pack that I bought a week before in it. Still never budged from 75. So I stuck it in the freezer to see. It took about 2 hours for it to drop 10 degrees! Very strange.Anyway the instructions are so badly written that my eyes didn't know where to settle to find how to set it up. I mean how many pages of info do you need to operate this little gadget anyway! I finally tossed the instructions aside and just figured it out myself. Seriously the instructions are just stupid.It's going back.

I have one sensor inside the garage freezer (not frost free), and one inside the freezer section of my fridge (frost free) in the kitchen. I mounted the display on the kitchen fridge. The garage freezer is one wall and about 35 feet away. The garage freezer maintains its set temperature a few degrees around 0 Fahrenheit. So does the fridge freezer, except about every 4 days its temperature goes briefly up to about 24 degrees. After researching on google, I learned that the behavior of the kitchen freezer is consistent with frost free freezers, which use a brief periodic heating cycle to melt away the frost, which drains to an evaporation pan. Based on this, I have good confidence that the sensors are reporting correctly, and I am now able to monitor the temperatures to know that the freezers are doing what they should. I agree with others that the manual is not very user oriented. It is too technical and hard to understand. But I am not going to dock the rating for this product because of that, because the controls on the product are very simple and self-evident.

Mine does a great job of monitoring a refrigerator/freezer that sits on an outside patio and is, therefore, a bit unstable temperature wise during the extremes of Winter and Summer. I'm an electronics guru of sorts so I had few problems setting it up and understanding the rather poor directions that everyone else complains about. My main problem with the unit is that it goes through batteries like crazy - the main unit averages one set of AAA batteries a month. To make matters worse, it does not give you a "low battery" warning which beeps every few minutes over several days like smoke detectors do. It just gives one rather loud series of beeps and shuts down. That's fine when I am at home and within hearing vicinity of the low battery alarm, but as luck would have it, this event often occurs when I'm away so I may not notice that the alarm is not functioning for several days. I'm in the habit of checking it every morning now and also watching the battery indicator. Since I've not seen any other complaints about this particular problem, maybe I have a defective unit. Otherwise, the unit works great for me. It saved a freezer full of food when the AC outlet ground fault protector tripped for some reason and has also alerted me several times to when the grandkids leave the refrigerator door ajar.

I love this!! I have spent MONTHS looking for someway to monitor the temperature in my son's room. Our furnace pumps too much heat into the side rooms so I've had to close and seal the vent. I use an ambient space heater but I still wanted something to alert me in case it became too hot or too cold. I bought a digital temperature alarm unit that didn't work and had to return it. Then I found this and it works GREAT. My sons room is on the opposite side of the house and it stays connected. If ever one of the sensors looses connection, I just walk it closer and it reconnects. It has alerted me once when the temperature hit the range that I set. Which by the way, is VERY easy to do. LOVE IT

I bought this to replace an Accurite unit that failed (display segments went bad) and it works so well in our travel trailer I bought another to monitor our secondary fridge in the garage. I hope it holds up better than the Accurite unit did. I will update down the road if it fails.

I use this to track the temperature in the freezer section of my kitchen refrigerator and in the freezer in the garage. I glance at it daily and keep an eye on the temperature range each freezer is experiencing. It works well; I tracked it with a reference thermometer in the freezer for comparison. I don't use the alarm feature. I keep the display unit on the refrigerator door. I have noticed that if I move the displau unit it will frequently lose its settings. It acts like moving it momentarily breaks the connectivity with the batteries in the compartment. So, I've learned to leave it in place.

Need this thermometer to check my downstairs refrigerator and freezer. It let me know that my freezer temperature was fluctuating 15 degrees which lets me know I have a problem. When sitting side by side, the temperature probes were 1 degree off from each other but I just compensate with taking readings.

As of today there are about 213 reviews and about 70% of them are for a SCREEN PROTECTOR. I believe the person who posted this product originally sold screen protectors with it to beef up the reviews and then when those sales soured used the same page for this product to. Once I realized this I instantly returned it.In terms of when I used it, it worked as intended although the setting min/max made no sense based on the instructions. The instructions are clearly written by someone who barely knows English.
