Consumer Reports backs Fitbit accuracy despite lawsuit
This doesn’t mean that the devices are flawless, or that the lawsuit has no merit. If your Fitbit occasionally underreports your heart rate by a wide margin, that’s a real concern — you could perform high-intensity workouts without realizing that you’re over-stressing your heart. And of course, there are questions as to whether or not the test is really comprehensive. The Consumer Reports study isn’t broad enough to completely rule out issues that could crop up with different body sizes and fitness routines. However, the findings suggest that the errors might not be as widespread as implied by the lawsuit. They may well exist, but they’re not necessarily easy to replicate.
