I buy this watch as a gift for my wife a couple of month ago , and she love it . I decide to go with the 205 instead of the 305 because it have all of the same function except for the heart rate monitor . the watch be a bit larger than most , so if you have smaller wrist you well have to get use to the size . the gp module locate the satellite farely quickly depend on you surroundings and be quick to give you you need information . so overall garmin make a good product and I would recommend it to anyone who love to run .
