I saw this system recommended on a FB group and the Amazon reviews seem favorable. So I decided to give it a try, especially since it has a WiFi connection, so the information display can be in the house, and an alarm. We can check the freezers' status at any time and the alarm will warn if we have a pending disaster.
It arrived well-packaged. The box exterior is plain cardboard with a plain label just at one end. No fancy marketing! I ordered four AA Lithium batteries at the same time for the sender units, which are recommended by the manufacturer for use in freezers. After installing standard 'Copper Top' batteries in the display first, then the lithiums in the sender units, the temperatures of each sender unit appeared on the display immediately. They were the same at about 72F.
To me, the instructions were clear, though it probably does help to be mechanically-inclined! I set the alarms for min and max temps and took the sender units down to the freezers. I hung them on the baskets with tie wraps as the included suction cups wouldn't have stuck on the dimpled freezer walls. The Amazon photo showing the silicone loop wrapped around itself is not very practical as the loop is small compared with the size of the sender unit and you'd have to really stretch it. Too much effort in the depths of a full freezer!
When I returned to the main floor, the alarm was sounding. The displayed temperatures were slowly going down as the sender units adjusted to the freezer internal temperatures, but were higher than my max temperature settings. I pressed the "Bell" button to put the alarm to sleep. The display seems to update every few seconds, not instantaneously.
After a few minutes, the displayed temps reached the freezer internal temperatures, which were just below 0 deg F. Each reading was slightly different due to being in different freezers of different makes and settings and the temps vary anyway within a few degrees as the freezer compressor cycles. 0 deg F is what is expected though for a chest freezer. I have my alarm settings at -20F and 15F for both freezers. The alarm won't go off for a few minutes if it reaches those temps. This avoids alarms when the freezer lid is opened to put in or take out food.
The signal display was indicating max. strength with the display unit maybe 20 ft (straight line) away from the freezers on the floor above. Moving at least double that into the kitchen, where the signal has to pass through a thick natural stone wall in the basement, as well as the floor structure and around various steel/wood heating ducts in the floor, the strength was still high. I was impressed, considering the sender units are also inside a cold, metal box!
The two small magnets on the back upper corners of the display unit, aren't quite strong enough to hold it firmly onto the refrigerator door. It slides down as the door is shut and there's a risk of it falling off and being damaged. I have it sitting on the dining room dresser, where it's out of the way, but visible. It could also be hung on a nail on the wall.
While a little pricey compared with other similar units (with more 1 Star reviews!), $35 is a small price to pay to avoid spoiling all the valuable food that is in the freezers!
So far the system is performing well and to design. I will update should anything go wrong!
UPDATE:
Several months in and the system is working just fine. After the first week or so, I noticed one of my freezers was 10 degrees or more colder than the other and unnecessarily so. I adjusted it and now I have comparable temps, though the later-purchased freezer has a wider range of temperature fluctuation , due to a less precise control system. Very pleased!

Full story:
We have a standup refrigerator-sized freezer in our basement (mainly because that was the only place in the house we had room for it). We've managed to leave the door cracked open a total of 3 times now in about 10 years, due to simple negligence, and have lost hundreds of dollars in spoiled frozen foods as a result. There's no reason this needs to ever happen, so after the last time a month or so ago, one part of my fix was that I wanted something to sound an alarm if the temperature rises too much.
Enter this simple wireless temperature sensor. Since the use case here is for a single-chamber freezer, and our fridge is well out of range 1 1/2 floors above on the other side of the house, I opted to just put both sensors inside the freezer. One is on the top shelf of the door, theoretically the highest temperature inside the freezer and the first location to start thawing if the door were left open. The other is buried deep on the bottom shelf near the back, which is theoretically the coldest area of the freezer. This way I get an idea of the effective range of temperatures throughout the freezer at any point in time. In case anyone's curious, there seems to be a fairly consistent 15F degree difference between the two sensor locations, plus or minus a few degrees.
Installing the batteries and connecting the sensors to the display unit was quick and effortless. I didn't have any lithium batteries on hand, so despite the freezer being below the optimal range for alkalines, I went with what I had and gave it a shot, knowing I could just go pick up some lithiums the next day if it didn't work. So far the sensors haven't had any battery issues despite the subzero temperatures.
Placing the sensors inside the freezer was also easy, although I couldn't make use of either the suction cups due to the low temperature or the wire shelf straps due to the shelves being thoroughly encased in frost and ice. That said, having them just sit on the shelves seems to work fine. The display unit is magnetically stuck to the front of the door and has had zero issue so far with the signal from the sensors punching through the metal frame. Both sensors show a very strong signal indicator.
I have not had an opportunity yet to test the alarm feature. I did reprogram the "refrigerator" sensor's alarm range to freezer settings and turned on the alarm for both. As pointed out in the manual, while one sensor is labeled as fridge and one as freezer, they're otherwise identical and you can adjust the alarm range for each one independently. You're also not limited to just cold temperatures - the nominal max is 158F/70C although the display only goes up to 99.9 in Fahrenheit mode - so you could easily monitor something other than a fridge and/or freezer with this if you wanted to. Anyway, one of these days I should probably take one sensor out of the freezer for a while and let it warm up just to confirm that the alarm is audible from another room.
Overall, I'm very happy with this purchase, especially considering the reasonable price.
Accurate, and easy to use.
Good value if one compares to the price of meat lately.
I only gave it 4 stars as the sensors don't have a low battery warning.
Just recently I thought my new freezer was going bad, but it then I remembered to check the batteries in the sensor. Replaced those and all is well now.
Easy fix is to replace the batteries on a schedule, like annually.
Ended up bying an simple analog gauge too to put in the freezer as a back up.
Top reviews from other countries
So, I resolved to stop it happening again and I purchased these. Reviews that are written after time and not when in the initial haze of consumer contentment always carry far more weight, in my opinion, and this is one such as I have had these since November 2022. I am writing this now because, thanks to these beauties, I managed to head off another fodder fiasco when a different fridge/freezer in the garage suddenly stopped: I fixed the problem before I had to throw anything away because I became aware of the issue in good time. At last - something I bought that actually SAVED me money !!
These are fairly straightforward to set up (although to set the warning alarms takes a little effort) and I am pleased to report that the batteries (two AAs in each) I installed in both sensors over a year ago - ALWAYS use lithium ones if you want a better experience ! - are still functioning just fine (although I have changed the three AAs in the receiver unit on one occasion).
I decided not to keep the alarms as I didn't want any potential beeping in the middle of the night, so I simply verify the temperatures every day. It's actually quite fun to think that you are checking on the temperature of an appliance outside of the house ! There is an easy-to-see record of the previous 24-hour's minimum and maximum temperatures at the bottom of the screen and one push of a button shows you all the lowest and highest temperatures from when you last reset the unit. All numbers are clear to read.
I do think that this set is quite expensive, though (and it was £60 when I purchased it), but one's choices are somewhat limited and at least I can show that they do work, so I guess it equates to value for money - especially when one compares it with a cost of replacing the contents of a well-stocked fridge/freezer !!
I have the receiver unit on the side of a fridge in the kitchen (decent magnets present) and the actual sensors are about 20 feet away in the garden behind a metal garage door; I have had no issue with signal strength.
And that's about it. As is my wont, I shall update this review if anything ceases to function as it should. If there is something specific that you would like to know that I have missed out, please ask a question and I shall do my best to respond...
