Review on 5-Pack of Kinyanco Mini Hygrometer Thermometers with Digital LCD Display for Tracking Indoor Temperature and Humidity in Home Office, Humidifiers, Humidors, Car, Greenhouse, Baby Room... by Micael Rau

Disappointed. 5 units, 5 different indications. No instructions. I can't figure out how to switch from F to C. I was hoping to check the temperature in 5 different rooms but none of the theses read the same. They all give different readings by more than degrees C and one has a 20% higher moisture reading than the others. But for the price it's not worth sending back. A little messed up. **edited** After a day of acclimatization they all now read to the nearest degree and a few % humidity of each other. Also, to change from C to F, you need to insert a conductive rod (large copper wire, etc.) into the hole on the back to activate the conductive tape on the board. I think there is a missing button that should do this.
