I use these to monitor the conditions inside water tight containers of 3D Printer Filament. The humidity reading is always acurate from my tests with dehumidifying. The size is perfect for clear wall containers to be functional and still allow reading. The battery life has been holding up well, and it is powered by cheap watch / hearing aid batteries. So replacement is no problem.I did get hot glue on one units sensors when creating a tight seal. It fried the unit and it permanently read 99° 99%. THIS WAS MY FAULT, but try not to block or saturate the sensor.

This is perfect for my 3D printing farm! I was looking for something like this because most options have huge humidity fonts that bug me. It's so much better when both the temperature and humidity readings are the same size. This makes it way easier to read at a glance. Glad I found this!

These work Great ! If you have an old heater thermostat that doesn't have your current temperature you will know the room temperature with these.

Great thermometers/hygrometers, responsive and easy to read. Can use in all sorts of applications, I used one mounted by my trail cam to read temp outside (with the camera on my trail cam!)

These mini hygrometers are an excellent value. I tested them in various enclosures and environments alongside another trusted sensor, and they consistently performed well, typically within one or two points of accuracy.I’m personally using them inside my cannabis curing jars to monitor the temp and humidity.However, I’m deducting one star because the batteries were active right out of the packaging. This makes it impossible to know how much battery life was lost during storage before delivery. Since each unit requires two LR44 batteries, replacing them could add up to become an additional cost if they have been sitting in a warehouse active for a long period of time.

Definitely have to calibrate when you first get it, but they hold the correct temperature and RH for my cigars very pleased. Shipping was on time no complaints.
