(CNN) – This year the word health is almost synonymous with the word Fitbit. Not only do you see these brightly colored bracelets at the gym or work, but the catchy commercials run frequently.
They promise to help get you in shape, but do the wearable trackers work? This month Fitbit was hit with a class action lawsuit, alleging fraud.
According to the suit two of the company’s heart rate monitors, the Fitbit charge HR and the Fitbit surge, don’t accurately measure your heart rate and that could be potentially dangerous.
Especially for people looking to push their heart rates past a certain mark. The suit surprised consumer reports, who tested and recommended the Fitbit charge HR and the Fitbit surge.
So consumer reports retested the devices and compared Fitbit’s products with another device that has proven accuracy, the polar H7 chest strap.
The consumer reports testers again found both Fitbit models were on point. If there was a variance between the polar device and the Fitbit, it was no more than three beats per minute, which isn’t big, but consumer reports noticed one exception.
The Fitbit charge HR would give more inaccurate readings at higher intensity workouts depending on where that strap was put on the arm.
If you follow Fitbit’s directions and wear the device in the place it recommends the monitor is accurate.
While consumer reports says it will keep an eye on the Fitbit lawsuit, it says it will continue to recommend the Fitbit Surge and the Fitbit HR.
