2 Pack Mini Digital Hygrometer Gauge Indoor Thermometer, LCD Monitor Temperature Outdoor Humidity Meter for Greenhouse Jars Incubators Guitar Case, Fahrenheit (℉) or Celsius(℃)

It does exactly as advertised. There's a four pack and in my opinion it's a remarkably cheap price for what it does. It works instantly out of the box. I've had them for a few months now and there are no issues so far. I keep one in my bedroom to tell me how humid the area is in there because I've had a lot of bloody noses recently when I wake up. And I keep one and my 3D printer room so that I know how dry it is in there. The display is very clear and easy to read. It is about the size of a 50-cent piece in circumference. Super awesome device for how cheap it was.

Great little hygrometers! Tested accuracy by using another hygrometer I had and it was on point. I use these in reptile cage and also in my incubators for chicken egg hatching.

As far as I can tell working great and I’m very happy it came with some small double sided tape strips and extra batteries!

I put both of them next to the indoor control panel of a more expensive weather station. These two devices and the weather station were not reading identically, but were within 1 degree F and one percent humidity of each other. For 6.99 the pair, including two spare batteries you can’t beat the value. I noticed the devices have a bezel construction so it appears they were specifically shaped to mount in the wall of display or storage cases so you could read the temp and humidity inside.

Great device to gain insights into temp and humidity from several different points simultaneously.

Firstly, this is an accurate device, and a decent value with additional batteries and double sided sticky pads. However, it will not sit flush/flat on its back. The photo appears to show that the C/F switch is internal, needing a pin or pen tip to insert into the hole. The actual switch is a plastic pin that extends outside the back, thereby preventing the device to sit flat/flush on its back without changing the C/F setting. While the sticky pads can be used for this to prevent accidental setting changes, it shouldn’t have to. Otherwise, a very good buy for its price point..

These are the absolute best! I started some seedlings and was unsure if the temp was OK. Not only do they show accurate temp but humidity % as well so I know if they need more water. Amazing!

Great price for the 2 pack. Like the fact you can change temp settings from C to F

Muy precisos y vienen con baterías nuevas. Funcionan muy bien y son sumamente confiables.

good and handy, its not so precise but serves the prupose and justifies the price. I kept two of these devices next to each other and there is 1% difference in humidty and 0.5% difference in temprature reading of both devices. Overall its good.

التغليف سيء المنتج لايوجد به اي ورقة او كتيب ارشادات وضع في كيس شفاف بدون اي تفاصيل لايبدو انه منتج اصلي ولم اتمكن من تشغيله

One of the two received was not working. I changed battery but still it doesn't work.
