I picked up this 2-pack to keep an eye on the temperature and humidity around my 3D printer filament, and they’ve been flawless. The readings are accurate, update quickly, and the display is super easy to read from a distance. Both units matched each other perfectly right out of the box, which is a good sign of consistency. They’re small enough to fit inside filament dry boxes, AMS units, or storage bins without taking up space, and the option to switch between Fahrenheit and Celsius is a nice touch. For anyone who prints a lot and wants to keep filament in ideal conditions, these little monitors are a great, inexpensive upgrade. Highly recommend. Read more
