Review on Thermometer Hygrometer Temperature Humidity Greenhouse by Andre Tenk

This device shows the temperature and humidity in the house. It flashes from one reading to the next. There's a small retractable stand on the back so you can place it on a table or attach it to some metal with a magnet. There is also a switch to switch from Celsius to Fahrenheit. When you get it for the first time, open the back and insert the battery in the right place to activate the readings. I'm happy with my purchase and it was relatively cheap.
