The watch band started out as good as any that I have used before. It did its job fine, but while I was riding my bike, It broke in the middle of the band. There wasn't a weak spot that I could see, It just split in two in the middle of the band. I don't know what else to say, other than be careful while you're doing an activity to be aware of this issue. It could be a one in a million issue, but be aware that it could happen to you when you're doing an activity.
