Rating: - Works well, just what I needed to monitor my heart rate.
Did not want a chest band so this watch was ideal for my needs.
Rating: - Works well with one quirk
European standard date and time is hard to get used to but watch works great
Rating: - Not having a chest strap is the best part
I have to say I disagree with "Habeck" regarding this product. Although I have a slightly different model than this one, the best part about mio is the heart rate monitor because I don't need a chest strap. All I had to do was take it out of the box, put my fingers to its face (there are two sensor buttons there) and bang... there's my heart rate.
