Contrary to some negative reviews here I have acquired this weather station. You do what I wanted. View temperature and humidity. Visually it is relatively discreet, albeit somewhat clunky but that's up to the AA batteries. They can be set up with the fold-out foot or hanging on the wall. The synchronization between transmitter and receiver takes a few minutes. Although there are Batteries, which I did, however, be replaced immediately because of Kontast on display was already very weak. I was already on the verge of sending the product back because the contact station was demolished after only one day. Distance about 5 m. A slight change in the transmission site but has helped. The radio transmission is running on the 433 MHz frequency band, the world's most widely used tape. This ISM band is available for use in the fields of industry, science, medicine. (ISM = Industrial, Science, Medical). It follows that the transmission path can not be exclusive, and thus disturbances on the radio link also can not be excluded. So before you send the product back, once test other locations.
