Tech company Fitbit is facing a lawsuit as a customer alleges their products do not accurately measure heart rate.
Kate McLellan, one of three plantiffs in a California lawsuit, told Today that she has found the company's products do not work as advertised. She said her Fitbit told her her heart rate was 114, which is very low and not the same result she got from the heart rate monitor at her gym.
McLellan says she was denied a refund from Fitbit after speaking with their customer service.
"She made it sound like it was my fault, like I was using it wrong or wearing it wrong," McLellan said. "She said it's not really meant to track your heart rate all of the time."
With that statement in mind, the lawsuit claims that Fitbit's advertising campaign is misleading, as it uses the phrase "every beat counts." Fitbit says its products are not intended to be scientific or medical devices.
"We do not believe this case has merit," a spokesperson for Fitbit said. "Fitbit stands behind out heart-rate technology and strongly disagrees with the statements made in the complaint and plans to vigorously defend the lawsuit."
Fitbit has run into legal trouble in the past, facing a class action lawsuit in 2014 after the Fitbit Force caused blisters and wrist irritation, as we previously reported.
