  1. Kathleen

    Super easy to use. Just one button to toggle between C and F temps and a humidity reading. I bought it to put into my bread proofing box to ensure that the temps and humidity were where I want them. The compact size makes it perfect for this!

  2. WK

    I wanted something to confim whether the A/C thermostat was registering correctly and what the humidity level in the house is. This works perfectly! It’s small, so easily portable. It has a built-in stand that enables it to sit on the counter without falling over. It can also be hung on the wall. It comes with a AA battery so it’s ready to use right out of the box. It arrived earlier than expect too. It is well worth the price (which is also great)!

  3. Gerald G. Richardson

    Not as accurate as I had hoped for, but is close enough to work for me.

  4. Kindle Customer

    With the 2 units side by side—each one gave different reading. Moved them to a different location and the same–different readings

  5. Geraldine

    Work great. Thanks

  6. Amazon Customer

    Compact and light, with large enough display for easy reading. The only thing missing is a button to light the display in dark surroundings, but that’s not critical. Excellent for the price.

  7. Elementary teacher

    The humidity readings on these match up with my expensive humidity gauge. These are handy to set in bedrooms.

  8. Krishna

    I’m a happy customer. Okay, it just arrived and it’s small and cute. Easy to read and comes with battery

  9. Christine

    Not accurate And little

  10. coolman

    Garage

  11. RNS

    Handy, practical, and quite functional as advertised.

  12. PJ14

    In winter I use these in my crawl space to ensure pipes are safe from freezing. I have found them to be very accurate.

  13. Kevin mack

    These came on time as advertised, and work right the 1st time! if you have a grow room or tent stick with this brand ( ThermoPro they seem to make things right!

  14. wolfpacker68

    Works, I like that it uses a aaa battery.

  15. Michael Williams

    Good product

  16. vickie ranieri

    Perfect size and very accurate

  17. Amazon Customer

    Used this hygrometer for a finished basement, it can be damp at times. Now I know temp and humidity level, and is accurate.

  18. Steve

    I like keeping track of humidity throughout my home. These devices are so versatile on where they can be placed, having a slot in the back for hanging on a screw, a fold out leg to act as an easel and even a magnet, so they can be placed on the refrigerator.

  19. JR

    I was ready to return them immediately because they were both off by 7 degrees based off the other two I have in the house. I decided to put them in the refrigerator just to see if they were closer to what my fridge temperature was saying and it actually was accurate, exactly what the fridge said it was. I guess these things just need some time to adjust or something. They now both work fine although they tend to be anywhere from 1-2 degrees off but I can work with that. They are easy to read and very small, which is what I was looking for.

  20. Bob

    easy to use

  21. Homeychick

    A little small to read at more than three feet. But I am old.

  22. Amazon Customer

    Stand or magnet mount. Used in different rooms in old farmhouse.

  23. Texas Customer

    I am using it as a refrigerator/freezer thermometer. Works well even in the freezer. Easy to read.

  24. Sussexguy

    I can’t understand how this product can be so inexpensive. It works well, though. The temperature and humidity readings seem very accurate. I like the stand and the magnet. Great product!

  25. William Ronald McCammon

    Just what I needed

  26. Little Willy

    There were two units in the purchase.I did notice that the temps were off by 1.5 degrees between the two units.That is something I can live with because was great price.The Magnet mounts work fine along with the fold out self standing bracket.Perfect for household temps. (don’t purchase for use in a nuclear science lab) LOL.

  27. Bob

    It needs more contrast to make it easier to read

  28. Hlnat

    It does what I wanted it to do

  29. shane

    great thermometer to use around the house, i use it indoors so not sure about the weatherproof part

  30. Book Goddess Leah

    use in my basement so can see temp down there plus the humidty. small and convenient

  31. Deborah K. Best

    It is small, but it looks good where we want it. As far as accuracy I couldn’t pinpoint it, because we use it for an idea what the temperature is in our home. Overall we are very satisfied.

  32. Nicholas G.

    Seem to be accurate and work great. I bought two and compared both with another thermometer and all are within a tenth of a degree or two from each other. Good enough for me. Wish I had bought a few more at that price.

  33. Rcoghill2

    The thermometer disagrees a few degrees from other thermometers. It is reasonable accurate. I am using it for garage and outside wall that concern me. I live in Alaska and sometimes it gets cold in the winter. It is good enough for my purposes.

  34. Amazon Customer

    Compact and accurate. Mounted inside new SteinwY piano

  35. Mitchell Anne Hagerstrom

    Small. I can move it around to different locations in the house.

  36. DON

    Easy to read and set up, but temperature and humidity readings vary among these two items and a ThermoPro indoor outdoor unit sometimes by slightly more than a degree. Still, close enough for me to use to ask my wife to please turn down her infrared fireplace heater.

  37. Amazon Customer

    I monitor temperature in each room of my condo. I would like them even better if values glowed/illuminated in the dark.

  38. Laura Davidson

    I have an old mercury thermostat and is sketchy. This helps keep things in line.

  39. AFC

    Both of these are from the same company. You would figure that they would get the readings right, or at least the readings could be a wee bit closer. You get what you pay for.

  40. Rosemarie Mezzo

    Small and perfect for the space where I have it.

  41. Parker Garms

    Perfect

  42. CHammer

    I placed the two I ordered on the same table top to compare, inches apart. After 20 minutes they were 4 degrees different and humidity differed by 5. I think I’ll go back to an old fashioned temp gauge. Not worth returning.

  43. rich vitagliano

    nice and easy to read

  44. Rick

    Simple easy to read, and accurate. I used it in my green room.

  45. Paul R Schneider

    It works great with no hassle. Reports accurately and operates on one AAA battery.

  46. Louis B.

    It’s hard to recommend this. In the beginning, it worked perfectly fine, but after several months, it decided to stop detecting the humidity. The temperature detection still works fine, though.

  47. Richard K

    Compared it to another unit reads exactly the same, so I’m satisfied with accuracy.

  48. Barbara B

    Nice small digital room thermometer. Only problem is you can see it in the dark; i.e., no back light.

  49. old man

    Precision of 0.1C (0.1-0.2F) is better than most. Seems quite accurate comparing it to other thermometers I have. Easy to read, and reasonable battery life.

  50. Joe

    Works as advertised. Both are consistent. A little off when compared to my expensive one.

  51. Hank Reisner

    Not very accurate!

  52. linda v

    Temp seems pretty accurate. Humidity seems a little low. Compared to my AC sensors. But disappointed no little face on mine. Feature missing… The display is easier to read to read than previous model, but happy face works on older model.

  53. spiceman

    Has possibly

  54. Karen

    Works great. And the price is right!

  55. Cobrasmach

    We has some hot and cold spots in out house, these thermostats helped us figure out the problems and our HVAC company came and reworked our air ducts. Also love the humidity features.

  56. GeneM

    Little smaller than expected

  57. john

    very cheap (why i bought it) but easy to use and very accurate..a good buy!.

  58. Ca shopper

    Seems accurate, price qas reasonable… the little magnet on the back is an unexpected plus, I can stick it on my reifrigerator or filing cabinet and it doesn’t take up space on the counter

  59. Queen Bee

    Can’t see it in the dark

  60. Joy Oflife

    It’s easy to use and comes with helpful instructions.

  61. Morris Kabani

    Good product and easy to use

  62. Ted Appignani

    Simple works well with know issues to date. (Have only had it for a month) Magnetic back is nice feature.

  63. Alina Murphy

    Well worth the price. I might just be back for another one.

  64. Tom Leonard

    liked it very much

  65. Captain

    I put these in several rooms throughout the house to check temps in each area, they were surprisingly accurate. With in a half of degree.

  66. Kat Mac

    Great little room thermometer- helps to know what the temp is for fuel saving and energy saving

  67. Thomas J Beutler

    Small and easy to read!

  68. JOHN CULLISON

    Love it. It would be nice if it had a nite time feature where it lit up.

  69. john farinella

    great product,keeps accurate temps and humidity

  70. Fransheska Hernandez

    Does what it says and helped control my son’s nose bleeds with the humidity reader!

  71. Doris Fisk

    ordering, delivery, packaging…all great

  72. Customer

    It works. Came with its own battery. My office is cold in the morning and now I can tell how cold it is.

  73. PHILIP FIRST

    The item was delivered sooner than predicted. It was securely packaged, and included a battery. I already have two similar instruments, manufactured by different companies, and the two are in agreement, both in temperature, and humidity. This item produces readings that are ~15 percent off, with temp being too high, and humidity being too low. The instrument is OK if you apply the correction factors.

  74. krhoff

    The product does what it is supposed to do. Compact and easy to read

  75. Tony Pinckney

    There are discrepancies in readings when multiple devices are side by side. And the humidity readings are pretty much useless.

  76. Gatgirl

    Small and accurate. Easy to use

  77. Rp

    It’s nice to know what’s cause the dry sinus and this produce is accurate and recommended to those who are in question about their air quality

  78. Jeffery Dressig

    I like how every 10 seconds it updates. It’s easy to read and very handy. It has a little stand and is magnetic and has a hole to hang it. I also like the little smile or frown if the temperature and humidity is too high or too low or in a good range..

  79. David

    Great product, works excellent and is easy to see. Use it to help govern where I have our dehumidifier set.

  80. Vivian Mayol Caballero

    It is very small!! I bought two of these thermometers before and they had more information.

  81. Jeff

    Easy to use. Easy to Read

  82. Liz H

    There is nothing I dislike about the thermometer. It tells the temperature of the room like it suppose to. Thx.

  83. yankee

    It is accurate but small.

  84. Maria J

    works great for our reptile cages & incubators, very accurate!!!

  85. Ken Kraujalis

    Not exactly right on but close enough.

  86. njep

    Simple, comes with batteries, works great, we have one in the garage and several rooms in the house. It’s nice that it shows the humidity also.

  87. brian g

    I had these in the shade (no direct sunlight) on my dining room table to check the humidity in my house. They worked great for the first month, then you can’t read them anymore. Literally 4 days after my return window closed. The humidity reading is completely illegible and useless now. It’s a shame because the size of these were perfect, now I have to throw them out.

  88. Muhammed Akhter Ahmed

    works good

  89. Walking Taco

    Great for price. Could be a little bigger but works fine

  90. Nolan C. Babcock

    I bought these to monitor rooms of the house to verify good ventilation when people complained about their rooms being hotter or colder and they work very well. Strongly recommend.

  91. Marcos Correa

    Very easy to use and the cost is even better!

  92. Sunshine

    Good product!

  93. JP (verified owner)

    This is the second Thermopro product I’ve bought, this a gift for my wife. She loves how easy it is to use and how she doesn’t have to guess when her food is done. It is a quick, accurate, one handed operation. Well designed.

  94. Sarah Eden

    The thermometer does not appear to be accurate. I am currently sitting about one foot away from the thermometer. I’m wearing a long sleeved shirt and a sweater. but it still feels cold, yet the thermometer was reading 74 degrees a few minutes ago! That’s certainly impossible, as I can’t imagine feeling so cold at 74 degrees! To test the thermometer, I moved it directly onto the windy window sill that was only 6 inches away from the thermometer, and the thermometer dropped to 65 degrees, which seems more reasonable, ‘though even at 65 degrees can’t imagine feeling this cold wearing a long sleeved shirt and a heavy sweater. I then returned the thermometer to its previous spot, and it’s now reading 69.7 degrees, ‘though the room’s temperature feels the same as it a few minutes ago and and I’m still feeling cold.

  95. Julie A. Brodeur

    Time will tell. Will report back as the corn grows.

  96. Kim H.

    Gives an accurate reading. Great for the price.

  97. HT

    Very accurate. Not too big. Simple enough. Magnet in the back enable to attach to ferro surface better than other brand I currently use. I would recommend others to buy with no reservation.

  98. Carol B.

    We have it in a very sunny room addition

  99. Alex

    Not sure about the stand. Seems solid. Seems accurate relative to others that are solid. Not advertised as weatherproof bit I have it in an enclosure with a Tegu lizard and it’s been showered with water several times and seems okay. I only have it a 4 because I haven’t been using it very long. I will submit another review in a few months.

  100. Sheila D

    Easy to read. They use AAA batteries which are easier and cheaper to purchase than the ones that use the button batteries.

  101. acatlady2

    It does the job of a quick temperature and humidity check but it is really small. Much smaller than the ones I bought for my other house.

  102. Jane Allegro

    We live in a motorhome and put these by our AC wall sensors. I wanted to see if they were reading the same as our main panel. So far, they are within a couple of degrees of each other.

  103. Richard James

    I have one in each bedroom to know the temp and humidity.

  104. Kindle Customer

    I really found this just the right size to use in my home and also my office. There are times that sitting at work it just got cold and now at least I know I am not imaging it. So this works very well. Very happy with this.

  105. Judy Grace

    The thermometer arrived on time & was as advertised. It’s small but I knew that. A button moves the temp reading from Farenheit to Celsius & back easily. 2 weeks ago I would have given it a great review. Then it stopped. First, it kept resetting to Celsius. A pain but not tragic. Then earlier this were, it stopped working ompletely. I replaced the battery. That worked 1 day; the next day it had no display but I repositioned the battery & it worked a few times. Then it was dead again. On the chance I accidentally put in an old battery, I got a brand new one & replaced it again. Same thing. I have barely had this thermometer 2 months– it was delivered 1/16 so it stopped before the 2 month mark, at around 56 days, considering it stopped earlier this week & Feb is a short month! But, you can’t contact their customer service after 8 or on the weekend at all. Sent an email & will see if they respond. But in my opinion, a product should last longer than 56 days.

  106. Siriphatsorn

    Do this have calibration?

    • CSTEAM (store manager)

      Hello,

      Unfortunately, this specific model device cannot be recalibrated.

      If you feel this device is reading inaccurately, please contact our service team at service@buythermopro.com.

  107. Jefferson

    Small, with magnets and perfect!

  108. Robin

    I purchased these in order to check the accuracy of my Nest thermostat. I didn’t think it was accurate. With both Thermo Pros I was able to set in different areas of the house to compare with Nest thermostat. The all give comparable temperature.The Thermo Pro is very reasonable in price and is accurate with both temperature and humidity.Buy it!

  109. Alfredo

    It works

  110. N. Voitik

    Our camper did not have a current temperature gauge. I put this in the hall next to the thermostat for the a/c and furnace which is not digital. Works well.

  111. Clifford Nelson

    People that expect these things to be right on are fooling themselves. To do that it would have to be calibrated and that would cost a lot more money, For the price pretty good, and using a AA means that it will last a long time. Maybe nice if there was a way to calibrate if you had a standard to use, but I do not.

  112. Tom K.

    Easy to read and ready to use right out of the packaging.

  113. Ed Engman

    A little smaller than I expected, but easy to install batteries and easy to read display

  114. proverbs23:19

    Bought this for our sunroom and it seems to be accurate. Nice that it is small but easy to read.

  115. Robert

    Works great

  116. SGB1959

    The device is much smaller than I was expecting. You must be pretty close to it to read the numbers.

  117. Jonathan Keating

    i put this in my grow room and it helps a lot. works great and simple to use

  118. GM

    It’s great to temperature and humidity in my apartment. It’s easy to read and accurate.
