Good product, Good price, Good buy!
Hey Prime Members, quick, honest review about this product. I bought them twice, first bought to try and liked them and bought more. Very accurate and the price is good for this quality product. They are small but accurate, I have checked. Like that they are a temperature and humidity unit, perfect for Florida. I even use one in the fridge and another in the freezer, no problem. If you are thinking about pulling the trigger and buying these, do it.

I’m Happy! (Pending Long-Term Dependability)
As you can see from my photo, they are VERY consistent with each other. The temperatures indicate within 1 degree of a very accurate thermometer of mine. As for the humidity levels, I have no other hygrometer with which to compare readings. But since they’re so consistent, and based on most reviews, I suspect they are accurate, or at least very close.
Readability is excellent if there is good DIRECT light on the screens. However, in a not-so-well-lit room the readability falls sharply for my older eyes. Even in a relatively well-lit room, the display isn’t so easy to read if it faces away from the light source. There’s a convenient push button on the back to go from Centigrade to Fahrenheit, or vice versa. Back there you’ll also find a convenient fold-down kickstand, and a plenty-strong magnet to attach the device to steel and/or some magnetic stainless steels.
I particularly appreciate that each of these are powered by a common, easy to find, AAA battery. So, I’m able to use my rechargeable Tenergy batteries – also bought here on Amazon. I can’t yet comment on how long a rechargeable will last, especially since they are 1.2 volts, not 1.5 like non-rechargeables. But, with a freshly charged one, the display is just as distinct/sharp as with a standard 1.5 volt battery.
So, I feel I can honestly recommend these for price, function and convenience. However, long-term reliability still remains to be seen. I will update this listing as time passes to let you know if they are holding up as well as I would hope.

Simple but effective !
These are great little thermometers ! Only take one AAA battery, and last a long time on that. Compact device, but large display is easy to read. They have slot on the back to hang on a nail or screw, but they also have a magnet in case you want to stick it on your fridge, and a kickstand for sitting on a flat surface.

You’ll wish you bought more
I now have 12 of these. I put them all together a few months ago to see how much they varied in measurements, and I was amazed. Temps agreed to within 1 degree and relative humidity to 2%. Incredibly inexpensive for units that work so well. Batteries are included, and so far have lasted 2½ years.

Accurate Information, small & reliable
This is my second 3-pack purchase of these terrific small thermometers. They are completely reliable and display consistent and accurate indoor temperature and humidity. Also works as a fridge or freezer thermometer.
Very versatile to use on a surface with its kickstand, to hang on a wall or to attach to a fridge or similar location via the magnet. Large numbers in the display are easy to read.
(Just so you know: No backlighting for night viewing. Not a dealbreaker for me.)
One negative: 3 batteries are included in the packaging and every one of them was dead and useless. Be prepared to supply your own fresh AAA for each unit. Battery you install will last long, but the ones supplied probably won’t work at all.
The 3-pack of instruments is a very good value. Handy to read metrics for those storage places like the garage, basement or attic. Nice gift for a new homeowner.
Mr. Roger H. Geyer –
Works well. Reasonably accurate. Easy to use. Easy to understand. Does what it claims.
It all was completely intuitive, except the button to switch between celcius and fahrenheit being small and on the back. And that worked great once I read about it in the instructions. I love that the batteries are standard AAA, and very easy to replace, including the battery door seeming simple to access, yet secure and reasonably rugged. So cheap batteries, rechargable batteries, etc. are reasonable options for this. Plus, supposedly the batteries last about 18 months (I can’t confirm this).
I used the modes with it propped up with the fold-out stand on a flat surface and with the magnet on my refrigerator door, and both were dandy. It looks like it would also hang OK for those who want to do that, but I didn’t actually try that.
There was a little booklet explaining the functions (in reasonable sized print with my reading glasses) and a list of support numbers to call, by country.
By getting 3 as a pack, I was able to use 3 close together (as a test) and determine they’re quite accurate in both the temp. and humidity readings, as claimed.
With a new HVAC system, I wanted a better understanding of the temps at the periphery rooms of my house vs. the central hallway, and re the humidity with the system running, and these handle that well.
My only slight criticisms are:
1). That the settings for “comfort” re the human face icon are arbitrary and appear not to be adjustable, so somwehat useless IMO. Seems mostly like a marketing gimmick to me. (For example, I’m skinny and cold natured, so “comfortable” to be would be a warmer temp range than the one they chose).
2). There appears to be no backlight or option for one, so if it’s dark you can’t see the numbers at all. Not a big deal, and especially given the batteries last so long (re their claim), but some folks might like that option (which might cost more, take more batteries, etc).
Overall, for the price, this was better and more convenient than expected.

Good, Compact Temp/Humidty Device
Definitely good for the price. Conveniently small, but clearly readible. It is not meant to be read from across a room, so folks shouldn’t expect that. Choice of either Fahrenheit or Celsius at the press of a button. Not backlit, but that would only drain batteries. Needed AAA batteries supplied. The three devices initially had very slight differences, but then all three eventually agreed after enough in-room stabilzation time passed. If they continue as is, they will be a great little buy.

Just what I was looking for. Works great. I recommend 5 stars

Produit fonctionne comme il se doit.

Works well, the only issue is the the screw hole is very small so standard screws do not fit.
Renne –
Great size (smaller, more discrete) product. Though not sure of it’s accuracy as the 3 side by side (for several hours) displayed different results.
