Purchased only 215E, belt with heart rate monitor (HRM =) and during the additional offer by Garmin 50th reimbursed or 165E in the end! Product received specifically in the announced time (3 days). Super watch, which differs from the Garmin 210 because of its bluetooth connectivity that allows you to connect wirelessly to the PC and especially his apple or android smartphone via the free application from Garmin "connect". This will load all their data in the cloud [...]. Attention during my first 10k competition, the watch calculates 10,560 km, therefore anticipate that margin of error combined with the distance to double the people to adapt your first time objectives at km. The battery lasts a long time, the GPS route is rather very loyal. The use of data and graphics, after having set the parameters of its shows, is a real pleasure. The watch holds a GPS signal in 15 seconds. You can see the differences in height and altitude on the Garmin platform or application, once the GPS data has been integrated into the map MAPS / satellite (on smartphone application) or other cards (via PC). HRM belt provided is adjustable to suit different physiques. In short, I was satisfied with my old Polar watch more basic, and I was not too convinced by the design of the Garmin, but ultimately I do not regret my purchase! Ps: You can also replenish your non-registered by the watch trainings via the Garmin website to measure the distance and other parameters. You can also add contacts Garmin users and challenge on objective, etc ... etc ...
