Indoor Outdoor Thermometer Wireless, 4.5 Inch Display Digital Hygrometer Thermometer Temperature Humidity Monitor with 330ft Range Sensor and Adjustable Backlight

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 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.

The display unit and the three remotes have been working just fine. I've got the display unit in my home office and the remotes (1) under the deck where it's sheltered from sunlight, (2) in the barn, and (3) in the garage. I didn't really want three remotes but I've come to value the extra information.The display is rather busy - little emoticons to indicate "comfort" - but it also shows battery strength in the remotes which is very useful as are the trend arrows.I'm happy with it ....

Overall I like this. My family uses it to see the temps and humidity levels in different parts of the house and outside.I don’t think it is 100% accurate, but it’s usually close. The sensor I use outdoors is the hardest to get an accurate reading on as I lack a fully shaded location to put it, so it often reads much higher when in the sunlight. I’m sure if it was in shade it would be more accurate.

So far this thing has been everything that I expected. I was buying the three remote sensors work. They seem to be pretty accurate cuz I have others like it and they all are in agreement with each other.I was surprised at how small the display is, however it says as clear as day in the description what the size is. I guess I just didn't notice.I like that I can unplug it and it will run off the batteries and then after about 10 seconds it'll dim. The screen will go out but a second. You touch the light bulb it comes back on and that same button when it's plugged in that same button is a dimmer switch. It's really pretty nice.It's small and affordable. However a very good bang for the buck, it's good value for the cost.

This receiver unit can take batteries OR be plugged to USB, a very big plus for me since all these batteries can be a real pain. Also, the sending units take 2AA batteries, another big plus over 2 or 3 triple AAA, which are not as long lasting. The screen of the receiving unit in the home can be illuminated brightly, low light or not at all at a touch. Very easy to set up and read, a wonderful change from the usual microscopic lettering, especially for older people or anyone needing glasses.

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!

This is my second UNNI with 3 sensors. I bought another so I can get readings from 3 locations outside and read those temps from 2 locations in my house. One sensor is in my workshop. The readings are sent and received flawlessly with no interruption. This is very helpful in determining what activity I chose to do outside or in my workshop. I've used various temp sensors over the years and the UNNI covers it all. Thanks, UNNI.
