In short, this is a child's toy that some women may find useful for a sham workout. Or for tech-obsessed teens. This is terrible news for sports. A regular heart rate monitor appears to be at least three times more costly. Still, this is true of all sporting goods. You still haven't uncovered the solution. Instead than thinking about what's absolutely necessary, manufacturers tend to pile on as many features as possible. The biggest issue is that it does not function when shaken. Does not detect a heartbeat!
