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 Jeff Driscoll

Don't waste your money. I tried setting the humidity using the online manual but couldn't set it for two main reasons. One was that the adjustment screws are attached to the springs and didn't even stay in place when I used the tweeter and readjusted them to hopefully tighten the spring a bit. It never worked. Another way to adjust was to use a jeweler's screwdriver that didn't fit in the slot. I ended up trying a razor blade but because the screw was too deep it was impossible to get it to work. Didn't even want to set up the thermometers which were a bit off.
