I was hesitant to try these fridge thermometers because of the mixed reviews.I am very familiar with the operation of these type of devices that communicate/pair with each other so I decided to give them a try.I bought two. Setting them up was easy and on the bench the temps read within 1 deg of all 3 sensors, the remotes and the base unit. I let them sit for a day. They were near other temp devices of a different Brand name. All worked perfect.Installed one in my shop fridge and it has been operational for a week and I see no anomolies.The other one I installed in my Camper, one sensor in the Lithium battery compartment and the other exposed to protected from moisture outside air. Working perfect.The display is a bit dim in low light like others have said. That is ok with me. The other MFG's thermometers that I have are the same way, maybe not quite as dim.The Magnets hold the base unit quite wellI currently have 5 other MFG thermometers running around our home and property.I do not use the alarms on any of them.I do pay attention to the base units.Battery install sequence.Go to a place away from any other devices that communicate like these units. 50' away is enough.Check your battery voltages before installing them. 1.6+ volts! If not get another.I use good alkaline batteries like Duracell etc. Never have had an issue with the freezer section of my fridges and freezers.Batteries into the base unit first. Check that the display is on.Install batteries in one sensor. Within about 2 seconds the red led should flash.The Base unit should display the temp of that sensor.If it does not... Remove the batteries from both and wait about 30 seconds and repeat the sequence.If all is ok then do the other sensor.I will return and re-review if I have an issue with these units.I like the price!Jim.

Updated Review:The sellers responded promptly with instructions on how to fix the problem. The main issue is that it takes 30 minutes or more after initial set up for the sensors to register with the main unit. Also, it takes quite a while for the sensors to get down to the right temperature- significantly longer than a normal refrigerator thermometer. But given time, the readings seem pretty accurate.I'm taking off one star because this info should have been in the instructions- I shouldn't have had to contact the seller. Also, the alarm could be louder. I'm using it in a basement freezer and I can hear it faintly in some rooms of the main house, but not others. I think it will do, but am puzzled about why they don't make these freezer alarms louder. After all, if you are purchasing a freezer alarm, it's probably to use in your garage or basement. You don't really need one in your kitchen fridge as you can tell when the power is out.**************************Original Review:I just received this product today and neither sensor works at all. I contacted the seller for help, and will update this review if the problem is fixed.

Great Product. Have used with three refrigerators to monitor temperatures. My appliance service technician recommended that everyone should have this product. I check it every day. Has temperature range settings and alarms.

Update: One of the sensors will not work at all now. Nothing I have tried, batteries, etc., has helped. The other sensor occasionally has randomly wildly different readings than it should. I only know this because my fridge has a sensor but because I was having trouble with the sensor I did not remove the sensor I had been using before. So my fridge one day suddenly went from saying 0 to 9 degrees, despite not having been opened once. The fridge sensor and the other sensor both remained at the same temp range of about 1 degrees. I don't have the box or I would send this back. I must have gotten a lemon. Very disappointed with this purchase.I loved the concept but the sensors are poorly made. First day one sensor stopped working. I finally got it working again and now the other one has stopped. Very flimsy connections to the batteries. I can’t get the second one to work. They also are off by a few degrees because I had another sensor I was using and I hadn’t removed it yet. It agrees with my fridge sensor but these sensors are about 2-3 degrees different. Very disappointed with this purchase. I didn’t even get three weeks out of them.

El monitor de temperatura es excelente. Fácil de instalar, puse los dos sensores externos en un refrigerador y en un congelador y proporciona datos al monitor en tiempo real. Además brinda información sobre la temperatura ambiental, al mismo tiempo que la temperatura de los sensores externos. La programación de alarmas han ayudado mucho durante etapas de apagones de corriente eléctrica. Recomiendo mucho el producto.

I love the fact that it shows the room temperature as well as the two freezer temperatures.Both are at different settings; deep freeze and just Frozen enough.
