Looked for a long time before I decided on this clock.
Wanted to find someone who wasn't that big but didn't want a fitbit. After many comparisons I had to try a friend and although I have a very small wrist, I did not think this became too big.
What the watch can measure I also experienced was very much like many other, more expensive models.
Have used the watch for a little more than 6 months and think it is comfortable to wear. Also appreciate that they are easy to get notices on eg text messages, calls etc.
Most practice yoga and pilates and for those activities I think it is good at measuring the pulse. Tried to swim with it once but find it hard to say how exactly it is.
The only negative is that it probably loses the heart rate measurement a little when I stay on hot yoga because of all the sweat. Then probably a pulse band would be better. I wasn't looking for a super-advanced clock but wanted to be able to measure easier training. If you train a lot and put high demands on your watch, this may not be the right variant. But for the middle trainer who wants to keep track of pulse, distance, sleep etc I would definitely believe this is enough. Because it is quite small, it is quite ok to have as a daily clock I also think.
I like the app too, easy overview and easy to connect with others who also use Garmin.
