I got this watch about a month ago. I find the belt to be comfortable compared to the old Suunto belts. It seems to be reliable in detecting my heart rate. It does not calculate calories burned like some other Suunto watches. The compass and altimeter are pretty accurate, although I have not had to try it yet in a true outdoor experience. Not sure about the barometer. The thermometer seems to not be able to account for body heat so I have subtract 9 degrees (F) if I am wearing it.
