Serious and reliable, this resort seems so far indicate very precise data. Personally, I have had no problems pairing and capture the outdoor module, as well as to receive automatic radio the exact time of the clock in Frankfurt. Ignoring orange appearance of the screen on the picture Amazon: This is actually a picture with backlighting obtained by pressing a front button !!! The screen is very readable, the icons are self-explanatory, and the solar panel above (additional battery) is a damn good idea!
