Review on 🌡️ Versatile 10-Pack Mini Digital Thermometer Hygrometer: Monitor Indoor Room Temperature & Humidity Effectively with Large LCD Display for Greenhouse, Home, Reptile Habitats, Humidors, Office, and Garden by Jason Rogness

I was looking for an inexpensive way to measure humidity. Yes, accuracy would be important, but I was planning on having 4 in a closed cabinet (1 on each shelf). I figured I could take average and call it good. As opposed to buying an "expensive" and counting the entire closet on it. To my surprise, they sounded very similar. I opened the package and watched her for a good hour or so. Another thing I considered is the "free" battery swap. With my plans, I figured I could use them until the batteries died, replace the batteries, then replace the meter, replace those batteries, then buy a new pack. I expect they will last a while only time will tell how long the batteries last. In the end I am satisfied with this purchase. At the moment I will very likely order again if the need arises.
