    • Great measurement device!
Color: White Size: TH1x1
Review Image by Konrad
I bought this to keep an eye on the temperature and humidity in my room, and it has been simple to use. The display is clear, the numbers are large enough to read from across the room, and it updates quickly when the temperature changes. It also takes up very little space on a desk or shelf. The humidity reading has been especially helpful for knowing when the room feels too dry or too humid. It is lightweight, easy to move around, and does exactly what I needed without any complicated setup. Overall, it is a useful little device for a bedroom, office, or any room where you want to monitor the air conditions. ... show more

    • Great Little Thermometers
Color: White Size: TH1 x3
UPDATE: The thermometers do not automatically reset every 24 hours - you have to manually reset them. Not a deal breaker, but the description is a bit ambiguous and misleading. If I had read all the reviews more carefully, I would have realized this before buying. I like the design and they are pretty accurate, so I'm keeping them. Further accuracy testing shows that temperature reads .5 to .7F high and mid-range RH is at +/- 2% - both well within the advertised specs. And all three devices read the same side by side, so manufacturing QC is good. I purchased the 3-pack of this item because the max/min values reset every 24 hours. I am very impressed with the accuracy and quality control of the devices. I set all 3 side by side along with a calibrated RH meter. After about 20 minutes for stabilization, all 3 read the same temperature and RH. Better yet, the temperature exactly matched the calibrated meter and the RH was within 2%! It seems the accuracy of these digital devices has gotten much better over the past few years and this product demonstrates that fact. ... show more

work as expected, and is accurate compared to other infrared thermometers. I use them all over my house, I like to know the temperature of each room, I have a few in my office at work, and I even have some in my reptile enclosure. They all work exactly how they’re supposed to, they display clearly, and I like how there’s no backlight so if you want to keep these in your room it won’t keep you awake at night. There’s a magnet on the back which also helps if you wanna throw them on the fridge or a metal surface, or you can use this built-in stand and put them on a flat table top surface. Super versatile, I love them ... show more

    • Very good. Easy to read. Accurate. Flexible mounting options.
Color: White Size: TH1x1
I like the look of it, I like the features and how it has both temperature and humidity and even keeps track of the highs and lows. I also like the large easy to read numbers and text. The temperate reading is accurate and matches other thermometers I have. The humidity is reading a little lower than my other humidity meter but I'm not 100% sure which one is more correct but, either way, it's close enough. You can place it on a table using the built-in kickstand. You can place it on your fridge or other metal surface being it has built-in magnets on the back although the magnets seem to be a little on the weak side so it might slide or fall off too easily if you hit it. You can also mount it on the wall using one of the 2 included screws. It even came with 2 plastic mollies for better securing the screws into drywall. I have mine mounted on the wall, using one of the included screws. I didn't bother with the molly. My only complaint whatsoever, and it's a small one, is that the background isn't as white in person as it looks in the picture. The manufacturers picture shows the high contrast between the black LCD numbers and the white background of the LCD. However, in real life, the contrast is much less as the background is not so bright white. It's a little less white. If you look at the real life pictures that some of the reviewers posted, you'll see what I mean. However, it's really not that bad, it's a very minor complaint just that it didn't totally match the manufacturer picture as far as the background whiteness. It's still easy enough to read, even from across the room. ... show more

    • Perfect
Color: White Size: TH1x1
I use this every night, it sits on my nightstand and I can quickly and easily read the temp + humidity. It’s definitely an essential that I’d recommend buying before baby comes. I didn’t want one of the expensive fancy ones that connect to your phone or anything, I just wanted a simple thermometer that I could easily glance at while my hands are full, and this device definitely delivered. It’s a little hard to see in the dark since it doesn’t light up but your eyes adjust to it. Very convenient, no complaints. ... show more

My office is always too cold or too hot. It's nice to be able to tell maintenance what the temp is in addition to the humidity (which makes a huge difference). Great product.

    • Works Well
Color: White Size: TH1x1
This is a nice little gadget. Temperature measurement has come a long way. It's nice to have the humidity reading too. The little faces that pop up underneath the readings are pretty cool also. I'm only seeing one right now. It's that one with the not smiling face (😐). This particular device is in a shed. I was just curious about the humidity readings in there but it's not too bad. Not a whole lot of moisture but not completely dry either. I also have another one coming that I'll use outdoors under an overhang so it won't get wet because it's not truly waterproof but I'm sure that when that one arrives, I'll get the same excellent results that I'm seeing from this one. ... show more
