Review on 🌡️ 2-Pack Indoor Thermometer Digital Hygrometer - Backlit, for Bedroom, Baby Room, Wine Cellar, Flower Room, Lab - Battery Included by Robert Ryokan

I bought a set of two of these devices as shown in the photo. In the first photo, two minutes out of the box. The second photo is about 10 minutes after unboxing. The relative humidity is almost identical. The relative humidity in the left block sometimes drops to 46%, so I assume they are within 0.5% of each other. The temperature is pretty close too - the difference is about 0.8F at most, sometimes less. consistent. Exactly? No idea. I don't have a good hygrometer. The temperature is within a degree of my oven thermostat - close enough. For a rough idea, that's fine.
