Product review (5 stars): Simple device that works great!
I bought a humidifier for our dry apartment but had no idea what the humidity was to know how often to run the humidifier. This was perfect! It told me exactly what the humidity was and even had a bonus of the temperature. I went to school for biology so have no issue with the Celsius temperature reading. I have another device that has the inside and outside temperature so this was just a supplement to what I already had. If you are looking for something with humidity and temperature and can't convert Celsius, I'd look at other devices but for a simple humidity ready this is great!  The humidity percentage is displayed in large font so is easy to read as well.
