Fitbit is the subject of a new lawsuit over its Charge HR and Surge models, with plaintiffs claiming that the fitness trackers do not have accurate heart rate monitors as advertised.

Three plaintiffs from California, Colorado, and Wisconsin said in the suit that "Fitbit defrauded the public and cheated its customers," CNET reported

Specifically, the plaintiffs alleged that the Fitbits significantly undercount users' pulses.

"According to the complaint, one plaintiff had a trainer manually count her heart rate during a workout after buying her Charge HR last year. While the trainer recorded a heart rate of 160 beats per minute, her Fitbit device said her rate was at 82. The other plaintiffs cite similar experiences with their Fitbit devices," CNET explained.

As The Telegraph U.K. explained, the "PurePulse" sensor on the Fitbit models use LEDs that reflect light onto the skin to detect changes in blood volume to calculate a user's heart rate.

In response to the suit, Fitbit released a statement of defense saying that the device is meant for users' fitness needs, not medical needs.

"PurePulse provides better overall heart rate tracking than cardio machines at the gym, as it tracks your heart rate continuously — even while you’re not at the gym or working out. But it’s also important to note that Fitbit trackers are designed to provide meaningful data to our users to help them reach their health and fitness goals, and are not intended to be scientific or medical devices," it said.

"We do not believe this case has merit. Fitbit stands behind our heart rate technology and strongly disagrees with the statements made in the complaint and plans to vigorously defend the lawsuit," the company added.

Fitbit unveiled a new model, the Blaze, this week that also uses PurePulse technology.

CNET noted that Fitbit has had legal troubles in the past, and issued a recall in 2014 after customers complained that wearing the devices caused skin rashes.
