Good accuracy, the station and the sensor indicate a difference of 0.4 ° indoors in the same location compared with other thermometers difference is minute (in 0.3 °). By cons it takes several hours for all it stabilizes. The humidity measurement also looks good. The hours of sunset and moonrise and sun by location are almost exact, consider changing the nearest city. Good reception, fast time and date. Easy synchronization with the sensor. One default, the display contrast really bad, too bad. You can find the exact altitude of your location to "Geoportal"
