Overall, this a good companion on your jogging course or on your everyday activities.
The pulse measurement works OK, but you have to place your index finger VERY gentle (barely touching it) on the sensor window.
The blinking heart icon indicates that the measurement process is going well. If the heart icon disappears - it means that something went wrong (usually the finger pressure is too hard on the sensor)
I have this watch for 14 days now, and it runs very accurately and it looks like the more expensive watches - which is a good thing.
The watch buttons are someway hard on pressure.
For that kind of money - you won't find a (much) better sport's watch.

Good watch and heart monitor for sports

How long is the watch band? What are the dimensions?

Worked exactly as described. Shipping was within the stated time. I have ordered several for friends and have had no problems with any.
