Review on 🌡️ BOEESPAT 2-Pack Mini Indoor Thermometer Hygrometer for Home – Temperature Humidity Monitor Gauge for Room, Kitchen, Patio, and More – Reptile Terrariums and Planting Room – Battery-Less (White) by Russ Freeman

Bought 2 packs. They were inexpensive, the right size, and didn't need batteries. One of these was very different from the humidity from the box, even after several days of inactivity. However, I was able to adjust and calibrate the watch face so it now works fine. On the other hand, the temperature was turned off for a few days, but then settled down to within one degree. Overall, while not perfect, I'm happy with the purchase and would recommend if the person buying has something to calibrate. versus.
