Less then a year old and it no longer works

My fit bit was amazing but after having it for under a year the battery became noticably worse until I am not at the point that it doesn't last a full day. I find it's charging more then I'm wearing it so it's not collecting the data I wanted to know for my health. Go with one for the higher models they have more features and last longer.

Terrible quality

Although I love my Fitbit flex and how accurate it is, the wristband has now been replaced 3 times as it keeps ungluing. Very frustrating and expensive!

I redeemed 1,250 airmiles in December 2015 for my fitbit flex. My fitbit arrived the week after Christmas, and I forgot about it! I pulled it out of the package February 2016 and it worked great. It is now June 19 and I have worn it for almost 4 months straight, taking it off only to shower and swim.
It worked really well - accurately measuring my steps and my sleep. Problem is - after

J'ai utilisé ce produit pendant environ 4 mois et je devais également utiliser le Polar FT7 lors de mes entraînements car le Fitbit n'offre aucun moyen précis de calculer les calories avec les fréquences cardiaques. C'est plus un gadget qu'un produit efficace pour celles qui s’entraînent.
