Product review (1 stars): good looking but very poor quality
I live in Sao Paulo, Brazil , and wanted a third themometer/higrometer to monitor temperature and humidity in my apartment.
The higrometer doesn't match the readings of the other two, the difference being more than 10 percentual points.
The so called " humidity calibration adjust" doesn't work.
Then after two weeks suddenly the temperature reading jumped to a fixed value of 80 degrees Celsius (same as 176 degrees Farenheit).
I tried the "temperature calibration adjust" that also is a fake: it doesn't work.
Pity: the product is good looking but the quality is not built in it.
I am very disappointed by the  purchasing of this product.
I had to give one star rating just because ZERO is not accepted by the system.
