After the first runs, I have to say that everything works as promised. The initial setting is done in 5 minutes (manual not needed), the satellites are found quite fast and the display is really top notch. The timing and other values can be accurately measured and displayed fine. After each kilometer light already humming the bracelet, oh again a new Pace (z. Ex .: 6:48). The platform Garmin Connect (free), one should use absolutely, because here the data is stored perfectly and you can also see on the map, the distance traveled value, as well as all relevant data to run. Bluetooth to my Samsung S2 is not possible, but transmission via the enclosed USB is not a problem. Last but not least on the subject of runtastic: Running I want to have my peace, no empty battery (GPS), and even with a clear display .. So do not hesitate, order now and tomorrow you can start running Sun :)
