Dear seller. Thank You so much for the lightning fast delivery of my order. After testing, I will add a feedback. I bought this in order to assess the need to buy a humidifier in the bedroom. The packaging is immaculate, like Kashcheev's egg from a famous Russian fairy tale.
As I promised, I am adding feedback. The gadget measures the temperature accurately. For this purpose, compared with an alcohol thermometer. As for humidity measurements, there is nothing to compare them with. The photo shows that the humidity is low. I Wake up in the morning with a dry nose and continuously sneeze. I bought this solely because of the hygrometer for the house. The next purchase is a humidifier for the bedroom. I highly recommend the store and seller.
Everything is ok
