Review on 🌡️ 2-Pack Humidity Gauge: Max Indoor Thermometer Hygrometer for Accurate Temperature and Humidity Monitoring in Bed Room, Pet Reptile, Plant, Greenhouse, Basement, Humidor, Guitar by Christopher Todd

Since there were two devices in the box, I wanted to check how accurate (or at least consistent) they are. I put them side by side on the table away from drafts, cold and heat. Temperature quickly stabilized at about the same for both, but humidity was 17% for one and 43% for the other. He hasn't changed much overnight. Our other hygrometers showed about 30% relative humidity. And one of the little magnets fell right out of the box. And the battery cover is difficult to open. And they use a disc battery, not regular AAA. Overall not a very good product.
