I'm totally satisfied: GPS signal is received quickly, true distance compared with other devices match exactly when running the data is easy to read (I do not need glasses as usual ...), operation is simple super, no superfluous functions update is simple and quick, great overview at Garmin Connect with many evaluations. For me was the re-evaluation "Pace" - these are the min / km - is great: I can use my speed constantly monitor - the next B2RUN can come!
