Great for monitoring multiple locations.
Works as advertised, replacing a unit from another mfr that failed when temps dropped below 0 F. Have not reached that point. With three remote units, we can track temp variation in rooms away from the thermostat location, as well as outside. Setup was easy. Also measures humidity. Base unit comes with a USB cable to light up the display, but no power brick. You need to provide your own, or have a faceplate outlet that includes USB connectors. Otherwise, everything runs off of AAA and AA batteries.

Clear display and super easy to use
I’ve been using this indoor/outdoor thermometer for a bit now, and I’m really happy with it. The 4.5-inch display is bright and easy to read, and the adjustable backlight is great when the room is darker.Setting it up was quick — the sensor connected right away, and the range has been solid. I can check the temperature and humidity inside and outside at a glance, which is really helpful for keeping the house comfortable.Overall, it works well, feels accurate, and the design is simple and user-friendly. Definitely a useful little gadget!

Works great and covers all over the house
This is a good size for a tight space. I keep it on my kitchen counter. Works great and with 3 remotes, I can also see temps all around the house and outside too.I found it easy to set up too.

Sets up quickly and works well
This is a nice unit and does its job well. The only negative is that it only goes down to 14 F which limits its use in cold climates for monitoring outdoors. ( that is why I rated 4) The unit sets up and pairs quickly with minimal user interaction. I am using mine to measure the temperature under my house where my water pipes are to be informed if freezing is a danger. I did have a plastic molding defect on my unit. I emailed support and a replacement came in 3 days. I appreciate that they backed their product. If your application fits the unit temperature range I recommend it.

Accurate and easy to read
Works well. Channel 2 was a little difficult to get to work which required removing and installing batteries multiple times. Unit and remotes have been working great now for over a week. Have remote 2 in motorhome about 150 feet from monitor and it is very accurate. Have recommended this to friends and family.

Great Way To Monitor Different Area Of Your Home
Worked perfectly for my needs. I have 3 zones I wanted to monitor temps for my RV. Display is easy to read and the unit was equally as easy to setup. The main unit is not overly sized and the remote units connected from a considerable distance. This is a great option for monitoring temps outside.

Good value and good for monitoring refrigerators and freezers.
We have 2 refrigerator freezers and 1 chest freezer, and I wanted something to monitor them especially considering the chest freezer is an inexpensive model and I have a little concern about it possibly going out. Setup was simple. I plugged in the display unit then pulled the battery tabs on the 3 sensors. Everything connected right up and I just lay the sensors on selves in the freezers.After I first had everything set up, I thought the sensors were having issues because the display would go blank. Then I realized I had the display sitting right next to my wireless router, and it’s signal was blocking reception. I moved the display about 5 feet away and everything worked fine.The display base is in the kitchen near one of the freezers. The other 2 freezers are in the garage, about 30 feet away with a couple of thick walls in-between. There have been no issues with reception. The temps on 2 of the freezers are set to zero, and on the chest freezer, -20. The readings on the display seem accurate. I haven’t set up the alarm function yet, so I can’t comment on that. I’ve seen other reviews comment on false alarms. One thing to keep in mind is that the sensors are reading the air temperature of the freezer. Every time the door is opened, warm air will flood the freezer and cause the temp reading to jump 10 or 20 degrees until the freezer cools the air again.The price is very good for a unit with 3 remote sensors. Be sure to get lithium batteries for use in very cold temps.

Great device, it just works. No messing around with Bluetooth, with connectivity, with smart hubs. You just plug it in, give it batteries, and it works.The accuracy is borderline, but for relative measurements as in is it getting hotter or colder, it’s accurate. Takes it at least five minutes to adjust to the correct temperature and humidity, which is definitely good enough for a forty dollar device.

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.
