Review on 🌡️ REOTEMP 5.75" Polished Metal Wall Thermometer Hygrometer - Analog Temperature and Humidity Monitor (20 to 120 F&C) by Dustin Lannan

I bought this for my camper so I can see how warm it is from the bed. The hygrometer is kind of a bonus - I don't really need it, but it's quite interesting to keep track of in different places where you're camping at different times of the day. I haven't tested the accuracy with any calibration, but it seems pretty accurate. At least it's consistent and I see you can adjust the needles if they don't read properly. I think the constant variable is the most important to me. It has a hole on the back that can be put in a nail and then I also put three small screws in the extra holes when I ride this thing on 4x4 trails since I sit on my truck. No complaints yet and takes trails, kids knock on it etc.
