I bought this for our RV refrigerator. We have a wired thermometer but I wanted a wireless type to get rid of the wire from the sensor to the display that runs under the door gasket. I was a little skeptical that a wireless thermometer would work but it worked so well I could bring the receiver in the house and watch the refrigerator cool down the night before we left for a trip. The display has magnets for mounting that don't stick to a our fridge (all plastic door), we just stick the display to our stove cover as its metal and right over the fridge. The remotes have two mounts; a suction cup and a spring clamp. The display has a min/max function, alarms and it's large enough to be seen easily. All-in-all its perfect for our needs.

I'll preface this by saying I bought this b/c my relatively new fridge seems to hold temperature poorly, so I've had a small mercury type fridge/freezer thermometer (hereafter referred to as "Mercury") since shortly after I bought it. The problem with these is that you have to open the door to read it, and I wanted something that I could have a Min/Max reading throughout the day to note down in case I need ammunition to use against the warranty company. Being able to monitor both fridge and freezer temps is a big plus!

BOTTOM LINE: for those not wanting to read my drivel below -- The AcuRite 00986, after a week of use, works great for me... note that I had no battery issues like some have had. See next part...

BATTERY TIPS: doing a Google search on battery characteristics, I found information [link removed by Amazon...] on Alkaline versus NiMH versus NiCd versus other battery chemistries. One of the very useful pieces of info was operating temperature range. Of note: Lithium operates down to -40C (-40F). Alkaline: 0C (32F). NiCd: -40C. NiMH: -20C (-4F). Well, I have a zillion NiMH rechargeable batteries for kids toys and since I really only care if the freezer goes above a few degrees F, then I figured I'd try NiMH for my sensors, before shelling out $$ on the Lithium AAs. Results: my freezer sensor has captured a temp as low as -13F, so I'd say the NiMH option was a smart move. Even if I have to change the batteries weekly, I swap them out with another set of NiMH and put them on the charger for a few hours. So, my advice to you is to get an inexpensive NiMH charger from somewhere ($10 maybe) and a package of at least 4 (~$7-10), but 8 would be nice, NiMH batteries. I'd recommend any low-discharge NiMH, such as Sanyo Enloops. If you really want to cheap out, get NiCd, but they don't have the capacity that the NiMH batteries do. I know the investment is a tad high upfront, but one set of Lithium AAs is $6, and it's single use. With the NiMH, you can use them hundreds of times, and with 2 each in your fridge/freezer sensors, the back-up ones could be in your kids RC car, flashlight, etc. You'll save $$$$$$ in the long run, if you switch your household to rechargeable in general for AAA/AA type applications.

Ok, all the important stuff over, here is the boring, wordy review/information:

I received the AcuRite version (I'm guessing the Chaney branding has gone extinct) of this product, opened it, installed batteries (more about the batteries later), and within seconds, the transmitters were sending temperature information. I let it sit on my desk for a while, and after the sensors stabilized, they were within 1 degree Fahrenheit of each other, and right at what my home thermostat was set to. Good so far!

I then moved to the kitchen and put the sensors in the fridge/freezer, and mounted the display on the side of the fridge next to the freezer. It probably took between 10 and 15 minutes for the sensors to stabilize at the fridge/freezer temps. I bought another mechanical dial type thermometer (Taylor Classic #5924) from Amazon so I could compare the results with the AcuRite and Mercury. I started my "analysis of performance" by placing AcuRite #2 and Taylor in the freezer, and AcuRite #1 and the Mercury in the fridge. They all seemed to line up well, and I monitored things this way periodically over the course of the next few hours. Because my fridge is my biggest worry, I then moved Taylor to the fridge as well, and placed it somewhere else in the fridge away from AcuRite #1 on a different shelf. This way I could tell if temps across fridge were consistent. Again, everything seemed to read similar temperatures, so I'm confident the AcuRite system is A-OK for me.

I've had this installed for about 1 month. Both transmitters and receiver are working well. The freezer chest transmitter is located on the basememt floor about 10' (below)from the receiver on the main floor and the 2nd transmitter is in my frige on the same floor (2nd) within 15'. All working OK. So far, I can recomend this product.

I found this to be an awesome product for the money and for even more money it would be worth it. I read terrible reviews about the Chaney thermometers but like the new LG Refrigerator I put this thermometer in they are both great. What customers have to realize however is that the temperature in either a freezer or refrigerator changes as the compressor cycles and as the defrost cycles. The walls where one might stick the suction cups are usually warmer than the interior. The wetted suction cups stuck hard and fast. Using a good calibrated other refrigerator thermometer and putting the Acu-Rite next to it on a shelf the readings were exactly equal. Then putting the Acu-Rite 14 inches away from that other thermometer and on the interior wall about 1/2 way toward the back the temps run from 36 to 43 depending. The main thermometer in the center ofr the refrigerator always maintains an even 34 as it is set for. Freezer set for zero runs from -1 to +6. Again normal operation. I have the readout module magnetically attached to the side of the refrigerator. It is not made to transmit through walls or into another room so if it works for you like that all the better. I like it on the side of the refrigerator.

May be I got lucky, but this wireless thermometer worked right away for me. Put the AAA alkaline batteries in the main, had the AA alkaline and lithium batteries ready and put them immediately in the fridge and freezer sensor respectively. Waited to see temperature shown in the main (80 and 80, from holding the things).
Placed the sensors in the fridge and freezer, temperature started to change gradually ( the sensors do not transmit the temperature continuously, I don't know what is the interval).
I am using this to monitor an old subzero that has alarming fluctuations in the fridge section, but appears normal when the repair service comes to check. The main shows the max and min so I will know what happened when I come back from work.
I suspect this system is like the wireless weather stations I have around the house. The outdoors transmitters usually fail in a year, or some are temperamental and do not transmit.
Anyway, I put the main on the counter across the refrigerator, just a few feet away.
If the system fails too soon, I will report back.
It certainly beats having to keep opening the doors to check the temperature or coming home to find 43F in the fridge and not knowing whether it went higher than that.
Incidentally, a subzero technical support person we contacted about new subzero models with digital temperature control told us that the new subzero refrigerators simply use an algorithm to show an average temperature. I don't know whether this us true, but if it is, I will still need an independent check even if my refrigerator had digital temperature display.

I'll keep it short and to the point. It works perfect. It is great to be able to adjust your temps to where you actually want them. The suction cups do not work that very good in my refrigerator but the clips hold onto the shelves just fine. It recommends a lithium battery in the freezer side but so far a standard battery is working fine for me. If you want a wireless unit this is the way to go.

I've been using this product for just over a month now, and I absolutely love it. I use one sensor in the kitchen freezer and one in the garage deep freezer. The receiver is about halfway between the two (maybe 15 feet from each unit) and works fine. I like that it records the highest and lowest temps, and it's easy to clear those (each morning if desired!). The alarms can be turned off if you don't want to use them. YOU set the alarm temps. Just make sure you buy lithium batteries for any sensors you want to use in the freezer. If you have trouble with the receiver, try taking out the batteries and then putting them back in. (Also mentioned in the user directions). I highly recommend this product!

After a typical trip to Costco, my refrigerator is often filled with over 200 dollars' worth of perishable food. The storage life of expensive meat and cheese is inversely proportional to the compartment temperature above freezing. At the same time, green vegetables can be damaged by freezing. Hence, maintaining the correct temperature range is important. The Acu-rite wireless thermometer helps immensely in this regard. Moreover, it adds an extra layer of safety when there is a power failure or refrigerator breakdown.

After having a problem with my refrigerator, it had to be unplugged for 48 hours until the GE repair person arrived. Using ice and an ice/salt mixture to keep the compartments cold, I was able to monitor the temperature of both the freezer and refrigerator sections independently. This gave me confidence about the condition of the stored food, preventing a substantial loss of money that would have occurred if the food was discarded.

For the price, the thermometer is a reasonable bargain. There are a couple of design improvement that the manufacturer should consider. Most importantly, the sensors need to be better sealed to prevent moisture from reaching the electronics. In one instance, water leaked from my ice tray onto the sensor and then froze. Unfortunately, the sensor could not be resuscitated. The battery compartment for each sensor has no gasket. This deficit should be corrected.

The data storage min/max is helpful, especially on the food safety front. However, there should also be a time parameter because the temperature can vary based on defrost cycles and opening the door. Presumably there is a sampling frequency - it is not continuous. But it isn't clear the exact length of the sample period.

In regards to others' comments about connectivity problems, I can honestly say there haven't been any. Other than a longer-than-expected communication delay when restarting the main device, there haven't be unexplained drops in communication. This is in a home filled with different wireless devices.

Given that thousands of perishable food can be stored in a refrigerator annually, the Acu-rite thermometer is well worth the investment. To put the math in the proper context, over a five year period that one would expect to own such a device, about 32,500 dollars (125/wk * 52 * 5 = 32.5k) of perishable food will be stored in the refrigerator. The 30 dollar cost with shipping would only equate to 0.09% or less than 1/1,000th of the food value. That would make the Accu-rite thermometer one very inexpensive insurance policy.

We bought $1200 worth of grass fed beef and a brand new deep freeze so we thought we better get a alarm since we keep the freezer in our basement. One alarm is for the freezer and the other is only for the fridge since you can't set the alarming beeper for low enough for another freezer. We bought the special lithium expensive batteries figuring we want to do everything possible to protect the meat. It was a little hard to find a place in the house it would read the sensors and we would hear the alarm beep. But we finally ended up having to put the alarm unit in our bedroom since that is basically on top of the freezer. It worked erratically for 2 months, would alarm about once every 10 days and say the temp went up 20 degrees when nobody opening the door or anything, never figured that out but then about a week ago it just stopped working. We reset it, changed the $10 batteries, stood right next to the freezer and no matter what we do it won't work. So this product ended up being a big waste of time and money. Not sure if it can be returned after 2 1/2 months or not.

Product works well for what it was designed for. Short range may be an issue. I use one in my garage freezer and one in my upright freezer in my kitchen. Had to put the receiver in the laundry room. Units are one or two degrees off real temp, but great for an alarm. Uses 2 AAA in the receiver and 4 AA (two in each receiver)
