good buy for any sport, not startup too complicated, I can not do without me, really convenient, good battery life, gives calorie aproximative having returned weight, race walk: average speed in miles, time has each km, time, and average speed displays. Only problem ...... gps is a bit long, predict the time by 5 minutes of research ... Do not regret my purchase especially for the price! 10 euros cheaper than intersport with free shipping !!! :))
