ThermoPro TP49 3 Pieces Digital Hygrometer Indoor Thermometer Humidity Meter Mini Hygrometer with Temperature and Humidity Monitor Outdoor and Room Thermometer

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.

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.

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.

The meters are fantastic right out of the box. They come complete with batteries and setup is a breeze. The display is very clear. I would not recommend them if you need exact measurements, however they are PERFECT for our needs. They were very economical and we just needed a general idea of what our humidity levels were in the house for health purposes. I would recommend them. Since the meters were not post on, I subtract just one Star.

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.

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.

Perfect for what we wanted as a simple temperature reading. Size is perfect as it is very unobtrusive. Display size is sufficient to read across the room. No bells and whistles (except it does both Centigrade and Fahrenheit), but all we wanted was a simple temperature. 3 at about $6/each is a great price. It was so good that we both 3 more so we could have one for each room and one outside.

Accurate recording of temperature and humidity inside our home
