Though these devices are intended for outside use, I actually used these devices to track the temperature in various parts of my office.  There were complaints about the variances and I wanted proof in order to make an educated decision about what needed to be done to rectify the situation.

They Work Great Indoors Too!!

[This review was collected as part of a promotion.] This  thermometer unit is fandadgumtastic, I have one main base unit which measures temperature and percentage of dryness in the air, then with it came three individual smaller temperature units tied with the base unit. They report to the base, I've got two inside the house and one other outside on the back porch in a cat community house. All units have different readings. I love this unit. 
If you want to know the differences in the temperatures in your spaces, you need this wonderful thermometer unit.

Geevon Indoor Outdoor thermometer with 3 remotes

After losing 28 rabbits to overheating one year, this has been a lifesaver. We can monitor the hoop house where the vegetables and produce are growing and the rabbitry for appropriate temperature and knowing when to fix it from the house. We really don't want to see another mass extinction from heat.

Keeping . Things at viable temperatures .

Very easy to setup... literally unpack and put the batteries in the house unit first and then add batteries into the outside sending units. I have one in a greenhouse that is about 75 feet from the house unit and it works perfectly. The other 2 unites are about 30 and 40 feet away and also work perfectly. Seems accurate when compared to my indoor thermostat reading and I had an old humidity display and that seemed to match. Each unit was within 1 degree and 1% humidity of each other when in the same location. Definitely recommend this package.

Very easy to setup... unpack and put the batteries

i have greenhouses and during the winter you have to monitor  the temperature.  im getting older and its getting harder to go out in to the cold. These are perfect cause i can see what my tempatures are in each greenhouse without leaving my house. i just love these.  Time saver very much.

love the ease of tapping the top for backlight.   I have double checked accuracy with a different thermometer, and its always within 1 or 2 degrees difference.  I made myself a cheat tab, taped to the edge to easily remember which monitor is where.  I would definately  buy this again!

Multi location thermometer/humidity

Excellent for keeping track of temperatures in remote areas of your home, especially in colder climates, when your not around a lot but gives you the info you need to make necessary adjustments to your heating system thermostat or insulating cold prone spots in your home or camp, RV, or shed. 
It can also be set to sound an alarm on a pre set temperature, hot or cold ….this is a simple system that works .

Remote temperature readers

I was well pleased with this product. I had read the reviews, and some people seem to have a few issues, but I found it work quite well. I initially got all of them sent together, and kept them in one place until all the temperatures were reading properly. I didn't notice the accuracy was very close. The temperature readings were within 0.2°F of each other.

The indoor temperature sensor on the display device seems to work well, but the remote sensors don't appear to be accurate. Sensor %232 is way off and it shuts itself off periodically. The display device has a loose connection. Every time I sit it down, the display and alerts reset, making the alerts (what I bought it for) useless.
I recommend buying a better built and more expensive product. With this product, one definitely gets what they paid for; a product cheaply made and next to useless.

The first thing I did after installing my batteries (not included) was place these sensors side-by-side on my counter to test their accuracy. As you can see in the attached photo, despite being in the exact same environment, every single one gave a different reading. Don't waste your money on this brand—they are completely unreliable.

Don't buy this brand
