I got this weather station from a friend who has the (user-friendly) predecessor, for his birthday. Although I am of the opinion that you do not need such a technical frills (I only wanted an outdoor thermometer), I have yet put into operation, due solely of goodwill. Now, after one and a half years, I have this thing now but banished to the attic. To function: The weather station works well and reliably, the indicated temperatures and forecast accuracy of 90%. If delivery of the outdoor sensor was broken, which was claimed by my friend and replaced without difficulty and fast by the supplier. For operation: Contrary to the previous model of this device has the control knobs located on the back top. This is more than silly, because every time you take this thing in your hands, you moved something without knowing exactly what. Then suddenly rings late at night, the built-alarm clock, the temperature display is adjusted, predicting rolled, ... This "unwieldiness" has led me to remove that thing again.
