Simply the best tracker of the moment

I have this bracelet for a month and I am fully satisfied.
I had doubts about the accuracy of the pulse sensor but having done several tests in parallel with a POLAR chest belt I can say that the sensor is very accurate.
sleep analysis is also part may be a little less thrust than the concurrency but it is enough for the average person.
Bracelet discreet, comfortable to wear, accurate and gives the time (not the case for all bracelets).

Furthermore the Fitbit app and website are very well done: clear and complete. It is compatible with MyFitnessPal.

Finally, the Fitbit team is very attentive and the service is very good will.

I recommend their eyes closed !!
