Wearable maker Fitbit was hit with a class-action lawsuit yesterday, just after the unveiling of its newest fitness watch.
In the suit, consumers from California, Colorado, and Wisconsin allege that the heart rate tracking in the Charge HR and the Surge, two products that came to market last year, is inaccurate by a "significant margin," especially during periods of intense exercise. The plaintiffs say that despite Fitbit’s high-visibility advertising campaign around the heart rate tracking in its products, the monitors don’t actually "count every beat."
