Great solution to monitor the temperature on insulin or GLP1 pens that are packed in a cooling travel bag with gel packs. Small enough in size to fit inside the bag.

The remote units connected to the app quickly when the batteries were activated. They are small enough to fit small spaces like a guitar case—which is why they were purchased. The app is easy to read and I can confidently monitor temp and humidity inside instrument cases. I can’t speak to durability yet but will update this if there is an issue. I have other Govee units to detect water leaks in the basement and they also work very well. I’m glad to recommend these units.

Love em I have 3 and will get a few more soon. Super compact, love the ability to quickly jump into the app and see the temp and humidity readings. Easy fit in my Humidors

The media could not be loaded.

Exactly what I needed for the small hydrostatic refrigerator that I have for my peptides. It allows me to track the internal temperature of the refrigerator without having to open the door to look at a thermometer. It also allows me to verify if what the digital readout on the front of the refrigerator is accurate, which I have found it is not. It allows me to make adjustments and track the temperature through the day.

Makes monitoring the humidity of my toys a lot easier!
