Works as expected for such a low price
The first photo is in the house with the 3 sensors and the display unit all together. As you can see from the 1st pic, the numbers donât align perfectly but close enough for home use. The 2nd pic is my $500 A/C thermostat ( I defer to its accuracy) taken at the same time as the first pic. The 3rd pic is with sensor 1 and 2 outside and 3 in another room of the house. The only real difference I am seeing is the humidity display. This can be impacted by airflow and may account for the difference. The indoor display is compact, easy to see and looks good either sitting on the mantle or hanging on the wall. Functionality is exactly what I was looking for. Very easy to set up and use. Just have posts of AAA and AA batteries on hand. Time will tell regarding reliability but I would initially rate this product a great value.

Very Good Value and Very Good Customer Service
1) WORKS! The main unit connected very easily to the sensors, and stays connected, even at a distance. The remote sensors, as well as the indoor sensors in the base unit, are accurate enough for household and outdoor/outbuilding use.For users that have been critical of accuracy … outside of expensive lab equipment, if you set up ten brands of temp/humidity sensors, in the under $150 range, in the same locations, you will get ten different readings.This incudes the well-known brands. This brand is at least as accurate as the others in it’s price range, and is very good for everyday, non-scientific use.I’ve had one sensor in a rained-on location, and one sensor adjacent to a dark stone surface that the sun heats to high temps. They are still working well. The price is very reasonable for all that you get.2) SERVICE! The customer service is GREAT! My system was working fine for a while but, although the readings were fine, I eventually had a minor issue where I couldn’t adjust the base station backlight to the dim setting while on USB power. I contacted the company and they made it right in a big hurry.

Great Thermostat w/3 Sensors
Great accurate thermostat with 3 sensors! We’ve had ours over a year now and still haven’t needed to change the batteries in the sensors. We plug the main unit in but also have batteries in it in case the power goes out. Nice large, easy to view, bright display with a backlight that can be turned on or off. Main unit picks up a sensor 300 ft away in our barn so we know what temp it is without walking outside. Other 2 sensors are in other rooms in the house. Love this unit so much we bought another one for our small guest house but forgot it would pick up the channel signals (1, 2, 3) from our other sensors (doh!). Bummed but that just shows how well the units work as they connect to the sensors very well and stay connected. Easy set up too! We stuck a sticky note on ours so we’d remember what room each sensor is in. Easily a 5 star product and no I wasn’t paid nor given a free product for this review lol.

Good reliable sensor
Good quality. Screen readability is fair. Better, close-up. Seems to work well, as intended. Battery life is good., remote sensors, easy to use and reliable.

Very nice, convenient. Lots of features!
Can’t validate battery life of transmitters but they use 2 AA batteries compared to most remotes that use 2 AAA instead which should increase battery life. However, there is a trade-off because the transmit interval is around 30 seconds vs. 60-90 seconds for other remotes. The base unit has a 5V DC input so it can be used with a standard USB charger allowing the back light to be on continuously without draining the batteries (3 AAA).The greatest feature of the transmitters (remotes) is they work on what appears to be their own ‘frequency’ (and/or ‘serial number’ logging) and do not conflict with other brands of sensors. (Most brands share the same frequency & channel assignments. If 2 different brands both transmit their data at about the same time, the base unit gets confused and starts displaying the wrong transmitter’s data instead.) My base unit has yet to lose the ‘connection’ with any of these transmitters nor has it connected to any of the 3 other sets I use).The base unit has a selectable alarm for each transmitter (zone) if the temp and/or humidity exceeds the user settable limits. The alarm is loud enough to catch your attention but not enough to wake you or be heard at a distance. Also, the alarm stops after about 30-60 seconds but the corresponding display will continue to flash as long as the value remains out of range. If the temp goes back to within the set limits, the display will go back to normal. It would be nice if there was an indicator to show that it had been out of range such as when used in a refrigerator.There are trend indicators on the base unit but seem to be too ‘sensitive’ to minor variations. The temp could drop from 34.1 to 33.9 and it might display a ‘downward’ trend. (I’m not sure of it’s algorithm but I think it could use a bit of tweaking and use a larger time sampling.)As with almost all sensors, the humidity range is from 20% to 100%. (However, there are some sensors that will measure below 20% – this base unit would display those, if it could track them.)I use this set for my regular refrigerator (both main & freezer areas) and my chest deep freeze and it works great.

Great Wireless Four Way Temperature Monitoring
I purchased this ireless thermometer system because I have a refrigerator / freezer in my garage and one in my kitchen, as well as a box freezer. I can effortlessly monitor the garage room temperature while making sure my refrigerator doesn’t poop out. I also watch my kitchen fridge and the room temp in my house at the same time. This has been a reliable and no-brainer monitor since I installed it. Great product. Great price!

Works great, easy to set up, easy to read.
Works great, ended up buying two units one for home and one for our RV to place the remotes in locations subject to freezing. Batteries in the remotes last about a year. There are setting you can program to let you know when temps or humidity hit certain levels. Would buy again (and did)

Super et fonctionne vraiment bien!J’adore le 3 récepteurs et dure très longtemps sur batterieJe recommande fortement

Passt …. hat keine Uhr (macht nix, sind etliche in der Wohnung verteilt). Macht keine Wettervorhersage (kann das Handy total gut). Keine Alexa oder WLAN Verbindung (kein Ãrger beim Einrichten). Aber die Temperaturen zeigt es an (und das wirklich zuverlässig). Keine Aussetzer, die drei Sensoren funktionieren sofort wenn die Batterien eingelegt sind. Reichweite ist ebenfalls mehr als ausreichend. Wackelkontakt an der Stromversorgung konnte ich nicht feststellen. Ich bin begeistert, einschalten und wissen ob man eine Jacke braucht oder nicht.

El botón para la retroiluminación no funcionó correctamente, cuando lo conecté por usb, la pantalla cambia de intensidad en un ciclo sin fin y no responde el botón. La temperatura es precisa, pero no la humedad aproximadamente -8% impreciso.
