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 .

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

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.

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

improved model from the first one I bought, also this brand, several years ago. So far it is easy to see the numbers in a bright room and seems to be fairly accurate altho it never matches the temp read out on my phone by several numbers. Not sure which is the more accurate reading. Have one sensor upstairs, one downstairs and one outside.

Easy to read.

Guess good enough, I set them all close together and got temperature variation of ± 1° (F) and ± 2% humidity.  I guess this is good enough and it is within the accuracy they  claim in the description.  I haven't had long enough to comment on resiliency in outdoor exposure.

Good Enough

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.

First of all the control panel is very confusing.  Never figured it out.  Second is that I am picking up my neighbors wireless thermometers.    When I take the batteries out of the sensors I am still picking up data from other peoples sensors.  There is no possible way I can do anything about that.  Good luck trying to understand the control panel.
