This was my entry into the world of watches after some very disappointing experiences with cheaper watches. I really like this one, I use it for running and the occasional bike ride. So far, it's on par with GPS tracking and pace. It has several different settings while running. It is very comfortable to use, the battery life is about a week, which is what I use it for, namely training every other day. Then the rest of the time it's just normal hours. The only issue I had is that the heart rate monitor is sometimes a bit inaccurate when running for a long time. It comes in the form or either at a very low rate when I'm walking up a steep hill and I know my BPM is much higher than the advertised 87. On the other hand, there are times when I walk at an easy pace and I get Readings of over 200 beats per minute. Which is clearly not me. So be prepared or just bring a chest strap.
