Ease Of Installation

Easy to set up and use with accurate results.

i have 5 currently working...kitchen, garage, back yard, "office",  %26 in my pick up truck (outside in the "weather").  Ordering 2 more.  Reasonably inexpensive %26 kinda' fun.  (Do we need coats?  Too hot to take the pup?...etc.)

walmart.com

Just bought this to monitor a damp basement found that it is much more accurate and easy to access. I downloaded the app from the App Store onto my phone easily and I have enjoyed using it much more accurate than the previous one. I had very pleased with the service.

Great product

The holy grain of thermometer/hygrometer I SWEAR BY THERMOPRO (ThermoPro If you read this love a HUB , like Bluetooth to wifi , so I can always have charts but they keep ‘em for 48 hours even these little ones only con no backlight but Bluetooth so I use the app . Great for plant tents, great for room temps they are amazing at ambient area readings I only trust these really they have not ever done me wrong ❤️❤️🏆

ThermoPro =❤️

Best temp/hygrometer I have. Extremely accurate (within  /- 1°F ) Same for the hygrometer. I tested it and over 12 hrs it only dipped 1% less than it should've been 3 times and for under 5 minutes each time. I've been using it for about a month now and it's never failed me. Plus it comes with a Bluetooth connection that tells you the present reading as well as keeps a 24 hr,  1 week %26 yearly recorded chart for both temp %26 humidity. The only downside with Bluetooth is you have to be within 250 - 300 ft. But that's why it's under $10. You can also set an alert notification for whatever temperature or humidity level you want. For example I have it set up for 70°F - 78°F. If it goes below or above your set temp it lets you know. You can do the same thing with the hygrometer. If you want accurate readings for a good price you can't beat this.

Best temp/hygrometer I've ever owned

[This review was collected as part of a promotion.] I can't compare this to others because this is my first purchase. But it is a needed item in my kitchen because I do a lot of baking and the humidity does make a difference and how much flour I need as well as leavening.

I bake alot

[This review was collected as part of a promotion.] Its perfect for plants that need to be a certain temperature or humidity. you dont have to keep going to plants to check them u can look on your phone app! Easy setup and use! definitely a must have

best hygrometer Bluetooth!

[This review was collected as part of a promotion.] I have purchased three of these over the last month, they work great. All three appear to be accurate compared to a known good source, however, battery life remains to be seen. Another nice feature is that the app did not require me to sign up for a service.

Excellent product highly recommend.

Great value.  Connects to my iPhone's blue tooth very easily.  Seems to be accurate.  The primary use for this is inside of my electric humidor.  The hydrometer that the humidor was less than accurate and needed to be replaced.  I'm planning on ordering another one for my 3rd electric humidor.  I highly recommend this low priced, high quality item.

Great Value

Needed to install the Bluetooth app and turn Bluetooth on (both are easy steps). Have to have a clear path to the sensor for Bluetooth to work. I put one in my vehicle and can check readings from my front door before leaving house. Good Experience - replacing an old ThermPro that LCD segments stopped working (it did not have the BT feature)

Good BT Monitor for Vehicle

This is a Bluetooth only unit. No real smart capabilities. Didn't like that my phone had to be bluetoothed to it to get the readings, meaning if I turned my phone off, or bluetooth off, I had to wait awhile for it to reset. Even when it's connected, sometimes it doesn't refresh unless you manually do it in the app.

Accurate readings, but no wifi

Setting up thru app was ok experience but so disappointed. It Gives wrong temp. Probably humidity too.

Waste of money
