Review: works well - These humidity and temperature meters are accurate and easy to read. Setup was quick, and the readings update fast. Perfect size for small spaces and great value since you get two. They also include 2 extra batteries so it should help last a long time. There is no backlight so it hard to see at night.
Review: Good for reading temp/humidity in bearded dragon’s cage - Working so much better than the other ones that came with my bearded. These are reading the temps and humid more accurately. I like that they come with batteries in them and then two extra as well. They are both very easy to read. They are the perfect size and don’t take up much space. They come with an adhesive to stick to the tank and that’s holding up well. So far so good. I’d recommend these

### ⭐⭐⭐⭐⭐ They work for me and are small and nice
*by M***. on December 3, 2025*

They work as advertised, I believe they show the correct temp and humidity but I'm not sure, I have nothing to work it against, the size is small enough to not be in the way and the brightness it pretty much what you expect since they don't have a light in them. I would say if you needed to know the temp and humidity then these are worth it.
