I have long hesitated before buying this model, there are much more expensive and too sophisticated, just wanted to watch my FC during exercise, enough, have downloaded the complete manual on the net (sigmasport.com ), more explicit than the one provided in the box, we have to study it to understand the operation and settings, then its fine. The chest belt does not bother me at all. The stated values seem correct. The color is nice for a woman, the bracelet for me too. I bought there about 1 1/2 months, to then see the length
